This is a tale as old as time. We did this in the late 90s at an office supply store. Every Sunday night changing price tags “ooh guess there will be a sale on resume paper in the next few weeks”. 1-4 weeks out we would increase prices on some items just to lower them back when the ad came out.
I mean I could but I have a nearly limitless supply of rabbits in my yard. Their fur makes great gifts. My plants love the compost I get from everything else. As a bonus the blood compost deters rabbits from eating my cabbage.
Funny thing, I can’t seem to find any type of vegan certification that is concerned with the use of animal byproducts or waste in fertilizer. A few specifically say they do not check fertilizer.
