New Merchants - BTC Refund Policy

[virtualfaqs]

Looks like new merchants may have trouble whether to refund in USD or BTC. Generally tender received is the same as refunded. BTC can't be refunded as USD because of AML policies. A lot can happen to BTC in 30 days. I believe most merchants are refunding BTC based on current USD value.

Can anyone comment specifically on Coinbase, Bitpay and Gocoin refund policies? Differences?

Depending on the merchant refund policy, is it considered fraud to ask for a refund if you get more BTC back?
