I'm a Consignment Convert — Here Are My Secrets to Shopping Secondhand

I'm personally partial to marketplaces that stock all inventory in a warehouse, otherwise shipping times to be hit-or-miss when coming directly from the seller. (Shipping times are especially slow when the seller is shipping from a country outside of yours, which is to be expected, but still undesirable.)

When shopping peer-to-peer, unexpected cancellations are also to be expected. You are, of course, ultimately given back your funds, and it's helpful that each platform credits you automatically without any additional action needed on your part.
