I purchased 4 OLG giftcards for $25 each which totals $100.
promo says you get a $5 SDM card for every $25 spent.
Cashier took $20 off my total so I only paid $80. I did not receive a SDM gift card for $20.
Back of OLG giftcard says “use for payment of lottery products and services” so I think it is valid for all types of lotteries from scratch tickets to Lotto Max to Poker etc.
