I told my non-mustachian family I needed help and paid for their stuff then had them pay me back. This only works if you know for certain they will pay you back.
It helped that I timed my credit card order around big purchases I knew were coming (new tires at Costco, etc.)
If you have the financial cushion and don’t mind being a bit of a hoarder for awhile I bought extra things I know I will need in the future. Ex. Vitamins, deodorant, toilet paper, gift cards for places I know I will use later or give as gifts.
Just make sure whatever you do to manufacture spending doesn’t add a ton of fees.
