I'm trying again to formulate exactly what our database should allow us to do, please let me know if you guys have any comments on the following:
# our database is designed to allow the following operations:
# 1. save a deal specific to a product/store
# 2. find deals specific to a product/store
# 3. given a product, find all deals associated with that product
# 4. given a store, find all deals associated with that store
# 5. given a product/store, find the price history associated with that product/store
# 6. given a product, find the price history associated with that product
