^§Every experimenter quoted one sticker from each row. Most of the stickers are printed on shiny foil, except the stadiums, teams, and players, printed on regular paper. Although we cannot have a formal test to check that the stickers quoted in each category by different buyers are the same, we know that sellers, in general, assign prices based on a limited number of sticker types. Vendors usually do this because having prices for each of the 670 stickers is an enormous cognitive cost for them, and it also increases the menu costs. Additionally, by the very nature of street sales, these are fast transactions, and sellers usually mention prices quickly when one asks for a quotation.
