Wow SKU changes like that instead of fulfilling paid orders should be illegal surely

"In the cancellation emails, Corsair apologized for the situation. The company stated that the product had been priced incorrectly due to a system error. "

LOL. Not updating the pricing on a SKU from a supplier is not a system error.

This is why suppliers change their SKU's on what are really identical products.

So they can raise prices without a price match.

So really the orders were rejected because the SKU for the component was no longer available, because the original SKU probably had a contracted price.
