I used a couple discount codes for the purchase I made that included this toy, making the price for the toy lower. In order to exchange this toy for another of the same, I need to somehow pay the $7.40 I owe toward the new toy. That's fair, but I just need to know how I do that.
When I return the item, can I put the money I owe towards the new toy in with the toy I'm returning, or do I need to pay it with a credit card on EF somehow?
Also, I'm not familiar with using UPS to send things. What am I supposed to do? Can I return the toy in the box I got it (it's a USPS box), or do I need to get a different one?
