Promotion is not valid in conjunction with other promotions, discounts or vouchers.
This quote is from the last paragraph of this page: http://www.sutllife.com/Promotions/
I am not sure if my understanding is correct. Does it mean "other promotions, discounts or vouchers" are inapplicable to this Promotion, that is, you can't get any further discounts other than the one that comes with the deal?
Many thanks in advance for your help.
