‘‘Pay-what-you-want” pricing has proven successful in some settings while failing to be profitable in others. I conduct a field experiment at a charitable bookstore to investigate what role the relationship between the customer and the seller could play in a pay-what-you-want price scheme. When subtly reminded of their participation in the store's membership program, members paid significantly more per book than without a reminder, while this reminder had no effect on non-members. Further, I find evidence that prices are sensitive to quantity chosen and evidence that is in line with a decay in prices over repeated purchases.
