So Sweetwater is out to fuck you now... gotta read the not very fine print:
For a 2% FEE on the TOTAL amount you can save on interest. So you want $5k of new-schnizzle DJ gear? Sure, its 0% as long as you pre-pay Sweetwater $100 on top of everything.... plus if you don't make the payoff due date, you get to pay interest FROM THE DAY OF PURCHASE.
Double whammy. Add Sweetwater (well, the shit-tasktik Synchrony finance company more likely) to the list of places to be wary of.
