Currently you cannot enter special characters in the address field. I was not able to enter my correct mailing/billing address because of this. My address has '1/2' in it. For example, 1234 1/2 Main St would have to be entered as 1234 Main St or 1234 1 2 Main St, neither of which are correct. This means I may not receive product information mailed to me, and it may be a problem with my credit card, as it will not match the address on file with my bank. This seems like it would be a relatively simple thing to fix.
