For older gliders - a canopy replacement can approach half of the total glider value or more. So more cost effective canopies are then required.

It isn't any less expensive to produce a canopy for an older glider. Nor is it less expensive to install them. Shipping from Yerrup, if coming from there, is the same.
Sometimes cheap gliders aren't so cheap.
Unfortunately that is just how it is.
