A typical inkjet cartridge prints around 190 pages. So at 15 pages per $1 this is like buying cartridges at $13 a piece, except way more complicated and obnoxious. Cartridges normally cost around $20 so it is still a slight savings if you're willing to deal with the hassle of counting your pages every month.

For me however, I give that whole plan a giant middle finger. That's way too much headache and hassle for a $7 savings.

But only if you print exactly 15 pages each month

They do roll over up to 45 pages, so it's not entirely unreasonable that someone would use all or at least most of their credits.
