They haven't replied me either, after I sent them a message they stated
I should get a response within 24-48 hours. That didn't happen. Quite a
disappointment not getting what was promised, 20% of $150.
They are still advertising for both coupon (as of right now), which
makes this even more strange. Tried to find a way to email eBay, but got
lost during all questions why I want to email them...
P20APP doesn't work for me either. I used the P10DESK coupon the other
day, however as previous reply states, I interpret the coupon
description as both coupons could be used.
