Steam Controller scalpers are asking for $300+ on eBay — Valve's $99 controller demands high price as pre-orders sell out almost immediately [Updated]

Valve’s new $99 Steam Controller sold out almost immediately after launch.

Scalpers are already relisting the controller on eBay for $300 or more, more than triple the retail price.

Some buyers also reported Steam checkout and payment errors during the sale.

The quick sellout points to strong demand, but also ongoing supply and purchasing issues for shoppers.
