When I went onto the tower website to order my microwave it came up with a 20% discount code on my first order. I kept putting it in but it wouldn't be accepted so I went ahead with the purchase thinking I would contact tower as I thought it was a blip. No it wasn't . Apparently because I was buying a microwave the code wasn't for microwaves. I was furious. If I'd of been buying a washer it would have come back the same - no discount on washers. Never again will I purchase anything from tower. Just can't believe they can do that. I contacted them a number of times to no avail 😡
