Got sent an email from Shell Australia which had a voucher at the bottom of it for a BOGOF same size hot beverage or iced coffee deal. They should have put more effort into making the voucher higher resolution but show it at the counter and the attendant should put it through (I would hope so!). Another issue is that the voucher is to be 'surrended' despite it being sent by email!
Hot beverages are $1 for small, $2 for regular, $2.50 for large. The Iced Coffee only comes in the regular $2 size.
Terms and Conditions (it's barely readable on the voucher!):
* Valid for redemption of a free small, regular or large sized hot coffee, hot chocolate, chai, tea or Urban Coffee Culture Iced Coffee at Coles Express alongside a purchase of the same sized beverage from 02/04/21 to 30/04/21.
* Limit one hot beverage or Iced Coffee per coupon.
* Not to be used in conjunction with any other offer.
* Coupon must be surrendered and is not valid if defaced, damaged, altered or past its expiry date.
I have to say their coffee really isn't that bad. It's good value.
