Rob - I didn't see a limit on xoom's website. I just picked $300 based on comments above. I'll try and send a higher amount before I come back down on 20/8. My friend confirmed the funds were in their account. No action was needed on their end. Xoom also texted and emailed both of us with status updates. This certainly beats waiting in line at Moneygram/Western Union locations only to be told (at times) that they a) are out of money b) your ID/paperwork is not proper c) some other BS reason(s).
Mine was simply a transfer to an existing NCB savings account. Funds sent by Xoom for pick up most likely have defined rules for pickup ID, etc. I do not have direct knowledge of those.
