EDU macbook pricing is wrong on website

I've noticed some issues with pricing on website where what it claims you are being charged does not match what rings up. This appears to be a programming error, but the result is that people are being charged amounts different than what they selected.

For instance, on EDU pricing version of the site, if I select 14 inch macbook pro with max chip, it says price is $2899 for the 14 cpu chip. It then gives me the option of bumping up to the 16cpu chip for an additional $270. If I select that option, however, it does NOT add $270, but instead adds $450, so it is adding money to my cart that I did NOT agree to.

I tested elsewhere to see if this is some BS thing they do in general to trick people who are on EDU site into paying full price without consent when they upgrade anything, but most (not all) other upgrades seem to work as the upgrade prices indicate they should, so this appears to be a programming error on their site.

I don't see any way of communicating this to Apple so they can fix it.
