Can someone tell me how long it usually takes to receive the email from TrustCash?
If you haven't yet deposited the cash, know that there are multiple services that offer this same service:
(deposit at a bank using TrustCash, deposit at 7-11, Walmart, etc.) using ZipZap, Moneygram, ec.
You can choose the Bitcoin to email service and Coinapult will use your deposit to buy bitcoins that you can claim via e-mail, rather than adding USD funds to an exchange and buying them yourself. This happens in minutes after you deposit.
