Can I exchange something here for the same price as listed online?

Yes if no receipt then they just give you store credit for what it is in the store and if u have a receipt then they would give you what you paid and in the same form

No

With receipt you receive exact amount paid & money back will be however you paid in the first place. With no receipt they give you the current sales price in the form of store credit. So if you don't have receipt & the item is now sold for less than what you paid you will only receive the amount it is currently. **Always save receipts** It's the only sure way that you will get back exactly what you paid.
