In this case, I mean by consignment “picks and chooses and may reject some donations” and by thrift “accepts everything (and consequently has a large trash bill).” Prices for consignment are higher than thrift, but there’s less digging to find high quality items. Consignment usually also gives some money to the original owner when the item sells (e.g. Karen’s Closet; actually this is probably the more central definition), though I don’t think the Discovery Shop does since they benefit a charity.
