WHY ARE THESE THINGS SO FRIGGEN EXPENSIVE! My supplier told me that alot of people have good things to say about the new "plastic" spikes/nails. They are 20 cents cheaper (70 cents a piece) then the metal stakes. Is it me or do these things seem unreasonably priced? I dont know, i just couldnt believe I payed $115.00 for a box of 150 spikes. Any thoughts or ideas to get these cheaper? thanks!
