In those times, I've found the best strategy in order of buildings is: Electronics - Boutique - Pet Shop - Toy Store - Jewelry - Restauraunt - Furniture - Market then Bus Stop - Bench - News Stand - Music - bench - Music - News - Bench.
It is a very addicting game to play even if I'm doing other things, just let it run in the background.
I've played Shopping Street through probably 10+ times on multiple sites.
