I was at Canadian Tire this evening and noticed that the Ziploc bags were on sale for $2.47. I had printed out two`buy 2 and save $4`coupons. One for me and one for my mom. The cashier asked me where I got them and I told her online. She then said that if I was going to use multiple coupons from prints online, then they all needed to have different barcodes.
What is the story with this. Is it true.
Thanks
