Instead of the sticker mule that pops up and dissapears with the weekly special in the midst of a customer trying to place an order, just have a "Flash Sale" link on your website. As a new customer not sure how to navigate, I missed a sale because it popped up when I couldnt deal with it, then it never came back at the time when I could think it over, so I didn't know how to take advantage of your offer. The next day it was no longer an offer, so I missed out on an introductory offer to try a new product.
