Appropriate Tip
New here and am hoping for some advice on tipping.
I have Instacart+ and use it mostly for same day Costco orders. I typically tip 10-15% on orders ranging from around $50-$200, with the smallest tip I’ve given being around $8 and the largest $40. I will tip more if the item is bulky/heavy, or if I have a large number of items, or if the service is super.
I’m going to be placing a same day Costco order for the $279 vacuum cleaner. It’s just one item, but bulky. What would be an appropriate tip? I’m not made of money but I want to be fair.
