Hi all,
A lot of places don't sell drops because even if they do cut to size, they make the customer take the whole sheet.
The place in Youngstown is Baker plastics. They do fabrication, so they keep their own drops. They sell drops at a reasonable price, but if you want cut to size be prepared to pay a premium.
Curbell and GE Polymer shapes are cheaper than Baker and closer, so do consider arranging a group buy through the club and getting enough people together to share a full sheet. Both places have cutting capabilities at reasonable prices.
