It depends if there is a way to return multiple items at the same time. That is the only cost effective way to return. Cost to return is based on package weight not the number of items in the package. I very rarely ever return a single item. I usually always return multiple in the same package, especially at Christmas time.
I will definately be purchasing less. I will have to be 100% sure an item won't need to be returned. Lots of times with the Q you can ask for an exchange, the item can be available and they still process as a return and charge the S&H.
I will be better off ordering from Amazon if the price is similar, in case it needs a return or exchange.
This can't be compared to Amazon - you don't need a printer for that, just a phone for QR code to show at dropoff and it is usually free returns.
