I’m pleased to say that I think at least 3 out of 5 codes (the first 3) should work internationally. Not sure about the last two.

Didn’t use any of them myself though, so I can’t make any guarantees.

Let’s start with the 3 codes which should work internationally.

First of all, here’s a discount code that brings the price down to $0.99:

gofdcca43

Next, here are two $1.99 codes:

dog199
jcvdf199a

And, finally, here are the two coupons about which I’m not sure:

dbcom249 (brings the price down to $2.49)
gtnic145 (brings the price down to $2.95)
