So I have done some SE in person before but I am not sure how to go about this and how successful it would be. I have a UE Mega Boom, a Fitbit Surge, and a Logitech headset. My plan was to go to the store and say that I received this product as a gift but already have it and would like a similar product. My hope would be to get in store credit. I have done it with clothing stores, but when it still had a tag on it. How successful do you guys think this would be? I wouldn't be doing all three at once obviously.
