Generally, I have a 9AM cut off for shipping. This means that if you order and pay by 9AM, your order will go out that day. Sundays and Mondays are my busiest, and on occasion the last few orders don't get to the Post Office until Monday evening.
Also, I get my inserts frm 2 separate markets: Cincinnati, OH and one that's out of town. The out-of-town inserts don't even arrive at my doorstep until Monday morning, and it takes all day to prep them for order filling (actually, I have someone who helps me with that so I can get as many orders out on Monday as possible!). Any orders including those coupons will go out Tuesday. These coupons will be noted as such, something like (Available Tuesday 2/23) so you know when you are ordering.
I get many questions about the Shipping charges (above) and would like to explain that there are a LOT of hidden fees that I pay to run this website. When I was forced to either close the site or re-evaluate the business model a few months ago, I emailed my customers to get their feedback. I also checked out what other Coupon Clippers charge, and am still WELL below what most of them charge:
