The college have emailed me with the details and price as quoted, so that's written confirmation, I guess.

I visit the College of Piping weekly, and I guess the only way to be 100% sure that's it's not too good to be true is to proceed with an order. The College of Piping do have much less expensive prices for lessons, bagpipes, books, chanters, etc, etc, than anywhere else that I know of as they are a charity and not a business, and rely heavily on unpaid volunteers who do the work, but I'm still kind of in the "too good to be true" area for this kilt price. It does seem to be just above the level of the fabric cost.

That's including VAT for UK buyers, by the way. If you are not a UK resident you would pay £245.79, (according to the price list), that's around 393 USD.
