Well the OP explicitly asked for HoHs and said " To create a hash that will allow me to determine if a store has a product I can use: "

I'm no native speaker, but for me this also reads like "if a store has products at all" which is quite complicated with a flat multi-dim hash.

I'm not banning multi-dim hashes both approaches have pro and cons.
