5% is not enough bro, i can get a double-pizza deal every tuesday at my country, so why not 100% for 5%, It's Domino by the way and i think pizza isnt suitable for some country , cause they're too fat . So this offer is not very good at all.
The 5% is taken after the best coupon possible is used. So you'd still save money. If you aren't interested, don't order.
