You'll have to go home and print out your E-Receipt on an 8.5"X11" sheet of paper to replace the 2"X4" receipt the store would have given you.
AND-—Many of those current receipts are printed on heat sensitive paper. They become UNREADABLE after about 6-8 months if not stored well, and still might fade away on you.
Excellent...
While I’M printing.... I’ve got a few more EXPENSES to count among my deductions.... scout’s honor your honor!
