Overview​

The platform uses Shippo API for:

  • Real-time carrier shipping rates
  • Shipping label generation (PDF, PNG, ZPLII)
  • Package tracking across multiple carriers
  • Address validation
  • International customs documentation
  • Return label generation
  • Pickup scheduling

For Buyers​

Viewing Shipping Estimates​

Shipping estimates appear on listing pages before you buy.

Setting Your Location:

  1. Go to Settings → Marketplace
  2. Add your shipping address (street, city, state/province, ZIP, country)
  3. Save settings

Estimates Show:

  • Carrier name (USPS, UPS, FedEx, DHL, etc.)
  • Service level (Ground, Express, Overnight, etc.)
  • Estimated delivery days
  • Shipping cost

Example:

USPS
Priority Mail • 3 days
$8.50

UPS
Ground • 5 days
$12.30

Estimate Accuracy​

Estimates are approximations based on:

  • Your saved ZIP/postal code
  • Seller's location
  • Package dimensions from listing

Final shipping cost calculates at checkout with your exact address. It may differ slightly from the estimate.

Estimate Caching​

Estimates cache for 30 minutes in your browser. If you see outdated rates, wait 30 minutes or clear browser cache to refresh.

No Estimates Available​

If "No shipping options available for your location" appears:

  • Seller may not ship to your country
  • Package dimensions missing from listing
  • Carrier doesn't serve your area
  • Contact seller to ask about shipping

For Sellers​

Package Dimensions​

Accurate dimensions are critical for shipping rates.

When Creating Listings:

Measuring Tips:

  • Measure the box or envelope you'll use, not the item itself
  • Add padding space (bubble wrap, packing peanuts)
  • Round up to next whole number if between sizes
  • Weigh with packing materials included

FAQ​

Does the platform charge shipping fees?​

No. All carrier rates are pass-through pricing. You pay the same rate the carrier charges directly. No platform markup or hidden fees.

Can I use my own carrier accounts?​

Currently no. Platform uses its Shippo integration for all shipping. This provides you carrier-negotiated rates without needing individual carrier accounts.

What if I want to ship on my own?​

You can. Enter shipping cost manually when creating listing. After sale, ship using your preferred method. Enter tracking number manually in transaction.

Do I need a thermal printer?​

No. PDF labels print on any standard home or office printer. Thermal printers (label printers) are optional but convenient for high volume.

Can buyers choose shipping speed?​

Not currently. You set the shipping method when creating the listing. Buyers see that method and cost. To offer multiple options, create separate listings with different shipping methods.

What happens if package is lost?​

Depends on who's responsible:

  • Lost in transit before delivery: Usually seller responsible, issue refund
  • Marked delivered but buyer didn't receive: Buyer files claim with carrier
  • Return lost: Depends on who paid for return shipping

Always use tracking to prove delivery.

Can I offer free shipping?​

Yes. Set shipping cost to $0 when creating listing. Build shipping cost into item price instead. Many buyers prefer "free shipping" even if price is same.

How do I handle overweight or oversized items?​

Contact carriers directly for freight quotes on very large items (over 150 lbs or 108" combined dimensions). Platform's standard shipping works best for typical collectibles.

Do I need to collect sales tax?​

Depends on your location and buyer's location. Platform doesn't collect sales tax automatically. Consult tax professional for your situation. Most peer-to-peer collectible sales don't require tax collection but laws vary.

Can I ship to PO boxes?​

Most carriers accept PO boxes. USPS always accepts. UPS/FedEx may not deliver to PO boxes depending on service level. If listing says "No PO Boxes", decline offers with PO box addresses.

What about APO/FPO/DPO addresses?​

Military addresses (APO/FPO/DPO) ship via USPS only. Use USPS rates and treat as domestic shipping even if overseas. Delivery takes 1-3 weeks typically.

How do I handle damaged packages?​

If you're the seller:

  1. Photograph damage before shipping (package received damaged)
  2. File claim with carrier
  3. Refund buyer or send replacement
  4. Carrier refunds you if claim approved

If you're the buyer:

  1. Photograph damaged package and contents
  2. Contact seller immediately
  3. Don't discard packaging (carrier may inspect)
  4. Seller handles claim process

Can I insure packages?​

Some carriers offer insurance. Platform's standard shipping doesn't include insurance. For high-value items, consider:

  • Requiring signature confirmation
  • Adding insurance through carrier
  • Using carriers with better liability coverage

How long do I have to ship?​

You set handling time in listing (1-30 days). Most sellers use 3-5 days. Ship within your stated handling time or buyer can request refund.

What if buyer's address is undeliverable?​

Package returns to you. Options:

  • Contact buyer for correct address
  • Reship at buyer's expense
  • Issue refund minus restocking fee (if in your policy)

Always validate addresses before shipping to prevent this.

Can I change shipping cost after listing?​

Yes, edit the listing. Doesn't affect existing offers. Active offers use original shipping cost.

Do I pay for return shipping on buyer's remorse?​

Depends on your return policy:

  • "Buyer Pays Return Shipping" - Buyer pays
  • "Seller Pays Return Shipping" - You pay
  • "No Returns" - No returns accepted

Set this when creating listing.
