Mine are mostly shopping related.
If I'm ordering e.g toothpaste I'll order 4 tubes, then won't need to think it about it again for ages, same with all inexpenaive toiletries. If I need to buy pens I'll buy a pack of 20, they soon dissappear but I don't care, I just buy more next time I'm at the cheap shop. The dc have multiple lunch boxes, if one gets left at school it doesn't bugger up my week
For dd's school coloured bobbles I ordered 5 times more than I thought she'd need, they get lost regularly, she'll have worked through them by the time she's finished primary, we're never stressed looking for bobbles.
Online grocery deliveries every 3 or 4 days, I never run out of anything, never need to nip to the shop.
Frozen onions, peppers, chillies and garlic.
