This is a quick but valuable post on discount and coupon codes.
We do a lot with coupon codes on our e-commerce site, for instance, we offer free shipping on all orders over $25 (our average product cost is about $20 so this helped increase cart size.
One day I added all the misspellings of coupon codes I could think of. Even made zeros the letter O. The result?
37 or 547 people entered the WRONG code. On average 7-13% of people type in the wrong coupon code. That’s a lot of missed sales. Most people won’t try the discount code again, especially in the direct response world.
Check those discount codes and try variances and flipping the words! It will definitely increase your sales.
