i used to do my groceries by myself, and do my mother's, also. Those days are long gone! I have 3 children, 2 of which are still home. When I go shopping, one of them comes w/ me. I am not able to lift a lot of things, or gather things from the high shelves. My sons are both 6 footers, so when they go they not only help me, but other shorter ladies.
When I was unable to drive, they all took turns driving me there and doing the dirty work.
A few yrs ago, the grocery store put a floor plan in one of its flyers, I cut it out and put it on my fridge. Due to the 'fog', there are times I can't remember the layout of the store - I go to my floor plan cut out. This way I can 'try' to put my grocery list in order, so if I'm lucky there will be no back tracking. And I 'hopefully' won't forget anything. I start my list the day after my grocery trip, so I won't forget any new items.
My children grab up the items, push the wagon, unload, reload, put in the car, unload and bring in the house. I put away what I am able to lift, they put the things downstairs in the 2nd fridge. When they are done, I am exhausted. Sad, but true. We leave at the crack of dawn so that we can avoid the large crowds, but all the walking around in the store is draining.
I have tried sending my DH and child for the trip, they always pick up the wrong things, even w/ visuals. It is easier (???) for me to do it once, then to go back and return stuff and rebuy.
I also use coupons and my store card for any and all discounts.
God bless. Alice.
