CVS

I purchased several lipsticks yesterday and was told I could exchange them if the colors weren't good. I was near a different CVS today and attempted to exchange them. An employee told me that I could do an even exchange for different colors. I spent a fair amount of time selecting colors and got back in line. I was then told by the manager (Stella) and the salesperson that I could not exchange them due to having purchased them at a different CVS. Since I used coupons I would only get .34 back and would have to pay $11.99 for the other colors of the same lipsticks. They said I had to take them back to the original CVS because it would mess up the inventory if I exchanged them at a store other than that.
CVS - it is ridiculous that in 2019 you do not have a system that allows an even exchange to be done at a store other than the original store when coupons were used.
Now I have to take additional time out of my hectic week to go to a CVS that's farther away so I can wait in more lines to exchange the lipsticks. At this point I feel like throwing them in the trash.
I used to get all my prescriptions at CVS but stopped because of the incompetency of the staff. I take VERY expensive medication (Creon) that costs several thousand dollars per month before my co-pay and Rite Aid is very happy to help me with it.
Lastly, the employee was curt when I was expressing my displeasure (not loudly but clearly unhappily) and attempted to rudely dismiss me with "thank you have a nice day" while I was speaking.
