I placed an order on 12/22/22 for a Fusion Pro 2 20-gallon aquarium on sale for $339.00, a heater for $89.00 plus a $29.00 shipping fee. Upon opening the box but not removing it from the packaging, I realized that I had made a mistake and it was too large to fit on the shelf it was intended for, as I thought I had ordered a different configuration, which would have fit on the shelf. I emailed and called the company on 1/2/23 about my mistake and offered to cover return shipping in order to exchange the tank for the proper configuration. They said that they would waive the restocking fee and send me an RMA# (I didn't realize that a restocking fee applied to exchanges, I thought it was only for refunds) if I placed an order for the correct tank on their website immediately, which I did even though the price for the correct tank had gone back up to $399.00 from $339.00 (with the holiday sale ending) plus an additional $29.00 for shipping. I figured I'd just eat this cost for the penance of my mistake. Upon receipt of the RMA# over email, I went to set up the return shipping. Return shipping estimates were all over $200.00 via UPS, FedEx, and USPS. I called the company back on 1/3/23, asking if they could send me a shipping label via their shipping account if I paid for it, since their shipping fee was $29.00, but they said that they would not do this. I requested that they cancel the order for the proper tank, since I can't afford the cost of the correct tank and over $200.00 for return shipping of the incorrect tank. In addition, they were going to charge me a 5% fee for canceling this order. My desired resolution is for them to be clear that exchanges occur a restocking fee just like refunds, and that return shipping costs are much higher for customers than the $29.00 that they charged to ship the tank to me. I will not order from this business again unless their policies are made more clear. I've attached order info and the most affordable return shipping quote.
