I find it weird to offer $29 off, rather than $30 off. The whole point of having a price end in 9 like $29 is to take advantage of people thinking "It's like $20" (cheap!) rather than "It's like $30" (expensive). But, since this is a discount you want to make it look as high as possible, not as low as possible.

I'm interested in seeing the source, do you offer a refund if I don't find it satisfactory?

It seems to be missing a "Sharing" folder in "xCode Project/"
