You'll have to sign up on comixology and fill out your payment details to buy comics there, but I think they sell Transformers comics on iTunes too separate from comixology, I just haven't checked it in ages, so for the time being I can only recommend to sign up on Comixology seen as I don't use iTunes. :)
Hi, I used TFTM deluxe Wreckage's head. Then, I sanded down the ridges on the upper sides of his head to mimic Megatron's buckethead silhouette. In fact, I previously used this one on my ROTF Megatron custom: [IMG] [IMG]
Yeah I've been dealing with them for a long time, and the shipping prices are a bit high, but I think because shipping from America is costly due to the distance between there and the gulf. It's not the same as shipping within America itself. But also note the prices of BBTS are also a bit more than other sites.
