Does anyone not know stores do this?
We even see this at the outlets when we go.
A trick is to use your phone (if you have a data plan) and check the prices elsewhere and online before you buy anything unfamiliar.
We hit the Old Navy outlet at Tanger in CT for certain things and because we know what a shirt costs normally and whether its good deal.
Many stores price match as well so if you find it cheaper via your phone at another store hit the manager and get a price match or sometimes even a 10% lower. Home Depot and Lowes do Price beating so its a good practice for tools.
