We often run errands on Fridays – my dh works nights, and he will often stay up a few hours on Fridays to get a few things done. Friday is payday, as well as either the last day at some stores for the flyer prices – or the first day at other stores for the new flyers….
Honestly, If you want to do Wednesday – do it, but remove almost all school from the schedule. Either plan for a 4 day school week, or plan for some school on Saturday. (If the kids don’t like that idea – point out to them that many PS kids have to run around with their parents running errands on Saturday. That is what my grandson does on Saturday – go grocery shopping with his mom, clean the house, etc.) – So you guys do that stuff on Wednesday, when the prices are better and the crowds much smaller (so it takes less time)
