You guys can save some money and make a free wire transfer to Squirrels at transfer.xe.com
It saved me about $100 on one BCU, for example. It will be nice when the acorns are available as bank wires are quite annoying for smaller transactions. If you decide to add a riser card or your friend asks you for an acorn a day late it's really not going to be nice paying those fees again. Plus you don't even have to drive to the bank if you do it this way.

Simply sign up, and then create a new transaction, filling in your grand total from the invoice where it says "you want:", after making sure USD is selected. It will calculate the amount in your local currency so you can compare to your bank at this stage.
Continue to the next screen, and select destination country "United States". Take the information from your invoice and fill it in here. For example, but please refer to your own invoice:
Recipient's name: Squirrels, LLC
Recipient's address: 121 Wilbur Dr NE North Canton, OH 44720 USA
Bank account number: 233220xxx (please copy from the invoice!)
ABA Routing Number: 044000037
(other bank details should fill in and match the invoice)
Reference: (Your invoice #)
Reason for payment: "Goods/Services"
Continue through the process to commit to this transaction at your quoted rate.

Then, at your bank website:
Create a bill payment to xe's partner company for your country using the 'pay to' as the name of the bill or payee, and your unique 'client number' for the account number. You don't need to put the reference to quote anywhere. This information will be in a pdf they have on the site and also e-mail to you.

Optional
Call xe and let them know the purpose of the transfer to ensure no hold is placed on the xfer due to any suspicions of money laundering

If your bank doesn't have the required payee to send the money as a 'bill payment', you can upload a voided cheque to xe and they will link directly to your account to debit it, but this will take about a day for them to set up.

My transfer went from my bank to xe (HIFX Canada) in 14 hours. The wire was sent 6 hours later, and payment was confirmed by Squirrels about 40 hours later, which is pretty good for having bank holidays in both countries this week.
