BBTS is ALWAYS my primary choice for grabbing TF's (I only buy online, never locally) and if they don't have it, I hit ToyArena, and if they don't have it, I go to ebay/Amazon/a few other online retailers.
I have Seibertron.com to thank for showing me that BBTS and ToyArena exist, otherwise my collection would suuuuuck. Instead, thanks to them, I've got darn near every Transformer that currently exists that I have even the slightest desire to have in my collection (save for a few ultra rare pieces that are practically never seen on ebay or anywhere else).
I know BBTS typically costs more. I don't care. I have yet to have any problems with them that were not resolved IMMEDIATELY and with exactly 0 hassle, and those issues themselves were extremely few and far between (I have spent many thousands of $ @BBTS).
I appreciate the price drop, but I already had all 3 pre-ordered even when the prices were at their highest before any of the price drops that took place in the last few days.
I am Alpha and Omega, the beginning and the end. I am that which is, which was, and is yet to come.
And you will know my name is MEGATRON when I lay my vengeance upon you!
