I check pretty much check everyday the ComiXology free comics list.
They have just added 700+ comics to the free list. (Thank you ComiXology and Amazon)
Please use the add all to cart option (I filled the cart manually the first few times, finger got tired clicking and I noticed the button), you will need to do this a few times as there is a 150 item cart limit.
The last title is a pre-order, so it may ask for a payment option if that title is added, just remove it.
Added them all to my pile of shame.
