All about oops!
You may see some product options called Oops A and Oops B. Here is what you can expect from purchasing those options (unless otherwise stated in the listing):
"Oops A" means that the product has a very minor defect, such being a couple of inches shorter than normal in any direction, having a small discoloration, having dirt spots/excessive wrinkles (which would go away with a wash), imperfect edges, etc. Expect to see a $1-3 discount from the regular price.
"Oops B" means that the product has a slightly larger issue that may or may not require editing or having to adjust how you use the product. This could mean it has larger spots or defects, holes typically no larger than a quarter, etc. The products are still usable, but the issue will be easier to spot than with Oops A products. Expect to see a $3-5 discount from the regular price.
We are unable to tell you exactly what kind of defect to expect beyond all of the above!
