Too Good to Go - Food App

I've used TGTG for over 2 years now and with very few exceptions, have got really good food. The one thing that irks me is the shops that forget to cancel and tell you they have no bag when you turn up. I feel that if there is a rule for buyers, the same should apply to stores.

My favourites are Whelans, the meat is excellent and you can freeze almost everything.

Sprout. They have large salad bowls that keep fresh for 2-3 days and big enough for 2

Cornucoppia, a rare treat when I can get my hand on one, always excellent

Tartine bakery, enough bread for a family for a week just slice and freeze the loaves

Queen of Tarts have very good cakes but the bag is small, no way the full value is 15€

On the other hand, Hansel and Gretel bakeries are very generous

I tried Keoghs cafe once, they gave me so much food I shared with the homeless I passed by

KC Peaches let you fill 2 medium boxes from their salad and hot food bars. Not amazing, but good enough

The Hopsack and the Fumbally are a bit random, they feel like lucky dip bags. Some great items, some not so great. I got 2 avocados once that were beyond edible, and a funky looking root veg that I assumed was a turnip

Aldi and SuperValu went from great to downright terrible, so I gave up

and if you’re out late and they’re available, boojum quite good

My last experience from Sprout on Exchequer street was a large bowl, another single portion of sweet potato in spicy mayo, and 2 slices of bread. Definitely enough to fill 2 of us up

Boojum are excellent. They recently put up their price to €5.05 but it's still cracking value

Their sharing plates are lovely. But some of them say they are not suitable for freezing (the chicken one in particular).

Sorry if this is already asked/answered, and it's probably a big secret :)

But how the hell do I get a Whelan's bag? What time of the day is the best time to go on the app? I've saved a few different locations as favourites but I've never seen them available, always sold out.
