I order every week and pick up and it works out well. Having them delivered is the same idea (you place the order online, they pick them, the substitutions work the same etc) but then a third party delivers them to you for a fee. I feel like if it's worth that extra few bucks not to have to pick them up then go for it. I am really happy not to have to do the shopping, esp right now with covid, but having them delivered pokes my cheapness button too hard.
