Many ask where they might find cards. This particular Auction company is spreading (I believe it originated in northern NY or in Kingston ON). For example, here is an auction in Atlanta GA https://maxsold.maxsold.com/auction/33499/bidgallery/page_Mg. Not all auctions have sports cards but some do. This particular one has the 1991 Topps set for sale.
I often see some of these in Rochester NY and have many in my area from Kingston to Oshawa. I have picked up several lots of cards including the Mantle Dormand Postcard and the prize card that was mailed out to hawkking today. Yes, like all auctions, prices sometimes get ridiculous but you would be surprised at how often I get things well below current prices. One day, I might even let hawkking know what the prize cost me.
You can search for auctions within so many miles of your hometown. You may luck in.
