I talked with the seller and he says that the postage is justified since he has to send them by expedited mail and that the $30 is the price as the package is a bit "weighty". For us in Canada even to send 1 chip costs almost $4.00 now(or more when you consider packaging), so $30 for 100 chips.....????. Looks like even you guys have to spend almost $2.00 to send a chip or 2 our way.
Signs of the times I guess. It sucks a bit.
Who knows,looks like an ok lot if you can get them at a reasonable price.
Good luck anyway if you decide.
