That's because MGW is the only authorized dealer for their own products as far as I know. The only way you'll get one cheaper than the $179 asking price is if you find a used one for sale.
They just sold a used one on ebay about a week ago. Seller said it had about 2,000 miles on it. Brought $162.50 if I remember correctly. Just shell out the $207 (shifter, inner boot, and 2 day shipping) and get a new one. You'll be glad you did.
