did there used to be a vitamin shoppe Store here ?

Yes

As stated by Emmanuel

The one inside the mall by Sears is GNC. Vitamin Shoppe is in front of Macy's across N. Main in the shopping area where FoodMaxx is, I believe Vitamin Shoppe is the store next to Starbucks.

The vitamin shoppe is across the street from Macy's at the mall.

Yes it's still there by sears
