I haven't done much thrifting lately, but I did find 8 placemats for $5 (our table needs placemats to protect the wood), and then on vacation I bought a tea pot and cookie jar in the pattern of my holiday dishes for $15 total, which is a pretty cheap "souvenir". I didn't need a t-shirt or coffee mug, but I will always think of this trip when I bring out the holiday dishes.
I also bought a set of vintage ironstone dishes for $75 from Facebook Marketplace. I'd been scouring the local thrift stores and either they didn't have anything I liked, or what they did have was overpriced and incomplete. This is service for 16 with dinner plates, salad/dessert plates, coupe soup bowls, cups and saucers, plus two each of serving platters, serving bowls, butter dishes with lids, salt and pepper shakers, sugar bowls with lids, creamers, gravy boats with saucers, and tea pots with lids. With over 100 pieces, it was less than 75¢ per piece, which my local thrift stores can't touch. Even if I'd gone the mix and match route at the thrift store, I wouldn't have gotten these kind of prices.
