I'm just back as well.
Shell, used coupon for gas paid in-store and only received 1 airmile and no promo code. Cashier assured me he scanned it, I heard a "beep" and saw him do it and after a lengthy discussion on whether he can tell on his screen when they scan ok (he can't), checking that I gave him the correct coupon etc., he told me none have been working for him today. I haven't opted in so I'll try that next.
Lowes, purchased the construction adhesive 295ml. Correct sku is on the receipt but no sign of any airmiles etc. If I recall correctly this was the case last year but they were "pretty fast" to post.
From 2018 STB thread "Lowes --no miles on receipt but miles posted (no StB notification but proper amount) "
Metro,
Baskets, mine has quite a few gift baskets, I'm sure they will get more based on past years' inventory. The only ones labelled at my store with 20 airmiles were the $34.99 size and weren't my favourite so decided not to purchase (I was only going to buy if I really liked something). There were quite a few Laura Secord, large nut baskets (not irresistible ) $50, Nestle mugs, teapot sets, forgot to take a picture and that's all I remember.
Floral, I've bought there in the past, girl went through their whole inventory with me and I'm thinking about a couple of items. Christmas trees will "likely" be floral as well so I might purchase there if they bring in some large ones (we usually buy Lowes' biggest size).
Catering/FreshtoGo, I ended up buying 3 large pizzas, most will go in freezer for when someone needs a quick snack/meal. Regularly $13.99, this week $9.99, bought 3 for $30, 66 airmiles (1 base+50stb on receipt+15 personal offer) with 25 coming later for using $10 cash. Excellent deal imho if you have pizza eaters. I've done this a number of times during prior promos. As already mentioned, receipt says "Metro catering 50". I plan to repeat offer on another card and also order a sushi platter when more are home here for Christmas.
