It seems DW spends more when she "pops in" for a $2.95 gallon of milk and walks out the $75 in groceries. That might not seem like much, but then do that 3 - 4 times per week and that starts to be real money. Ditto on the trips to the thrift shop - $80 once a week, not so bad. But $80 3 - 4 times per week starts to add up. The latter seems to more "shop" therapy than buying things actually needed.
You are absolutely right OP - she should do 1 big grocery shop once per week, and if you also shop 1 other grocery store, make that 2 trips total per week and that's it. I swear, your DW is my DH - every time he runs out to "grab just 1 thing," he spends $50 on garbarge - like junk food and crap we don't need. I buy the same groceries every week. I never waste money on crap because I have that 1 time to get everything, so I don't F it up. Put her on a budget - I think for a family of 3-4, if you eat at home everyday, $175/week should be enough to cover EVERYTHING.
And, to cut back on the trips to the store, I do "Subscribe & Save" on Amazon, where I get a hefty discount on essentials like paper towels, diapers, toilet paper, wipes, and K-cups by having a regular delivery once per month. It's probably cheaper than Costco, and delivery is free. If you sign up, that's less excuses to go to the store because you ran out of whatever.
Finally, how shit! She spends hundreds of $$$ per week at the thrift store??? She sounds like a shopaholic. That is insane. It should be more like 1 trip every month or 2, and that's only if you need essentials that you cannot afford like you have no kid's clothes that fit or you need a new table - not to just browse. In fact, IMO, nobody should ever shop to just browse.
