I didn't wait to order mine from Tower. Went ahead and ordered on Friday. With CC no cash really out of hand so no big deal that both radios are on the CC for a week or so. My Amain price was ~$500 after $40 coupon and $10 in Amain bucks. If you didn't use a coupon then it's a no brainer to return it and buy from Tower.

Few things to consider about Amain returns though:

1. You pay return shipping.
2. CSR for some reason said I should ship it back myself instead of just refusing delivery on the package. Said UPS charges Amain more for delivery refusal than what I would pay to ship the package. If I refused delivery that fee would come out of my refund. Seemed weird to me about the refuse fee costing so much.
3. Unclear to me if Amain is going to charge me with the initial shipping since it was free. Not a huge deal if they do since I was the one that changed me mind.
4. Officially Amain charges a 15% restocking fee if you want a refund as opposed to store credit. That is pretty outrageous for an item of this price.

I talked with the CSR and he said they would waive the restock fee as a one-time courtesy. Not sure if I will take them up on that or just do the store credit. Amain has always treated me well so I may just do the credit.
