I think the reason why Shop ‘N Save has the Wednesday only coupon is because  all the local grocery stores start their new prices (sales, deals, etc…) on Thursdays. So, not only is a $5 off coupon a good way to get customers to return and spend at least $30 but they could buy products that the store may be hoping to move, before the new products and new sales begin the next day. At least that’s what my theory is of this whole deal. And hey, I saved $5!
