I have worked in a hobby shop for over 22 years. Just for fun, I looked up the price of 1/64 ply. The prices mentioned in this thread are consistent with what is available to dealers. True, there are places to buy it direct for less, but typically the dealers don't get any discounts from those vendors. I can't fault anyone for wanting to pay as little as possible, but remember the hobby shop prices are usually set by the manufacturers or vendors, not the stores.
