Target sells Reynolds baking cups for around a buck – use the $1 coupon in 6/23 S for free baking supplies! Note that the foil are much more expensive ($1.37) than the paper ones (97¢), butTarget is clearancing out the paper variety, so you may or may not be able to find them.  Of course, the coupon doesn’t expire until 9/30, so plenty of time for stores to restock.
