Query: Price seems to keep getting more expensive

My friend's dog really loves these chews - the chews themselves are fabulous. However, they keep getting more expensive and harder to find, which makes them less and less of a value, both because of the time to locate them (and their myriad similar products - more than once the wrong ones were purchased, tho I don't think the dog seemed to mind), along with the price. I would definitely recommend them for large dogs who go through smaller chews like they were nothing.
