The most expensive band aid

I'm not sure if anybody else experiences this problem, but if I don't wear my Doc Marten boots continuously for a year or so they rub when I start to wear them again. I wear my cherry boots everyday, and I've been wearing them to work as well. I wanted to start wearing my purple boots instead so my cherry ones wouldn't get yucky from work. I wore them last week and they rubbed all day and I got a big sexy blister from them. So I went to the shops the other day to buy some bigger material patch band aids. I was in a hurry and quickly grabbed the ones I wanted and some tea, paid for them, threw the receipt in the bin on the way out and went home. I had to work early the next morning, and before I put my stockings on, I went to put band aids on so I could start wearing my purple boots and break them in again. I open the box, and there is only ONE band aid in it! One! I paid $3 for one band aid. And because I had already discarded the receipt, I couldn't even take them back. Things like that should not happen before 7 am.
