I wonder how that happens, did she just forget to scan the coupon? I thought that as long as the coupon is scanned, the 20% is deducted automatically without the SA having to manually do anything to apply the discount.
That specifically hasn't happened to me, but something similar has. I bought a Julianne which was supposed to be 30% off of $458, then an additional 20% off with the coupon. Well I didn't get the 30%, so I paid $458 - 20% when it should have been $458 - 30% - 20%. I'm going to try to get that fixed tomorrow. I do believe mine was an oversight though, I think the 30% just didn't apply in the system or whatever. I bought a lot of other stuff with the Julianne so neither I nor the SA noticed that the total price was a little high. I'd hope your SA's aren't "accidentally on purpose" forgetting to apply the discount, that would be horrible!
