I've had two(2) incidents, recently, where the manager changed the terms of their promotional coupons after an employee had already acepted them as presented.
In their current promotion, they were giving consumers coupons giving a 25% discount for transactions that totalled over $20, or over $40. The former gives you a $5 discount, while the latter gives you a $10 discount.
In the first case, the total value of the cleaning exceeded the total value of the $40 coupon, which should have resulted in a $10 savings, but the manager decided to reduce the savings to $5, by choosing to divide up the cleaning into groups, one of which was over the $20 amount.
In the second case, the total value of the cleaning exceeded the total value of the $40 coupon and the cioupon was accepted by the clerk (and stapled to the incoming order). During checkout, the manager decided to decline the coupon as not applicable to the type of materials originally presented.
Now I'm quite careful to make sure I comply with whatever rules are printed on promotional items and I have no problem with restrictions that are in place BEFORE I reach the store. In this case, I consider both events as fraudulent.
I've checked the Page the Cleaner website and there's no way to contact the franchise owner, or anybody above the manager who is implicated in these cases.
