Indochino has released a limited run of their apparently very well selling Premium Windowpane Suits. The two suits in blue and grey are now available from $729 as 2-piece suits and at $829 for the three piece version including a vest. The suits are medium weight (320g/m, almost a bit on the heavier side) and made from premium Reda fabric (an Italian mill). The price tag is hefty, but as usual if you have your fit profile optimised and you have some disposable income, these are good choices.
If you are looking for a lower priced suit, there aren't any on sale now that I would know of, but you can always check this page and see if any items are available for a discount (currently two vests).
