I have been using Venmo to transfer large amounts of money to my wife for a while now. She still uses a CU from her hometown because we get an awesome interest rate (2.4%) and get great monthly dividends. I transferred 2999.99 a few times to her account to maximize the dividends from her CU. My first attempt at MS I bought a MCGC from a Kroger store, and after the MO was declined at the PO, I put the card into my Venmo to send to my wife, and it went through just fine. I haven't had any issues with using Venmo, but I won't use it for MS because of the card limit.
