I've happily ordered from them in the past as they're one of the few companies that do larger sizes. I always remembered to skip the month, so that wasn't an issue.
The issue has been recently where items haven't arrived after 3 or 4 weeks and you get through to a US call centre who only work from a script and won't investigate.
I'm waiting for refunds on 2 items and you can ONLY contact them by phone.
They imply you can contact them by email, but you get a bounce back telling you to ring.
And to cancel, you HAVE to speak to them.
