Price for the above information: $9.99
Overall I absolutely agree that some of the pricing in classies looks silly to me, but forum rules basically say bite your tongue unless someone is outrageously gouging. If someone is looking to buy stuff in the over $100 zone, shame on them if they haven't done their homework on current price and availability for what they want to buy.
Some people are impulse buyers. They want Cool
mod X asap, and if they are willing to pay near list, or even a premium, that is their choice.
A given buyer may be acting on impulse, or because they know the seller is in a tight spot. (yes, there have been sales where buyer was explicitly willing to sell it back to seller in the future, essentially a loan to a friend).
Everyone on ecf is supposed to be an adult, and information on available products and prices is certainly readily available here.
