These were mentioned some months ago, for the competition in April, but have finally appeared this month in stores.

There are three new Transformers Hoodies -

Black Decepticon "shield" logo on light grey ($40)

Red Autobot "shield" logo on dark blue ($40)

White "breast-pocket" Decepticon logo on black ($40)

Looks like there are only limited sizes on these, from XS to XL.

JayJays are also having a sale, which includes some of their Transformers clothing.
The Hoodies above are on sale for $30 (save $10)
And two of the T-shirts (Megatron/Planet Enemy & Optimus/Big Rig) are half price (from $20, down to $10)... BUT if you buy 2, you get one free. That means, 75% off for those two.

I couldn't find an end date to the sale, so probably just ends whenever they run out of stock, or whenever they feel like it I guess.
