Don't know if anyone else has picked up on these bags from Westford Mill, available through Ralawise.
Westford Mill WM305 Polyester Packaway Tote
They print up well and look good (only used the Surf Blue colour though with Vector image which had yellow, another with red,blue and pink) but Black should show up on the Red, Pink or Royal and the Surf Blue of course :-)
Currently on their RalaDeal at 20p each.
I don't work for them, but use them as a supplier often.
