If you can hold out for an expo, often there are "expo prices" that are a good deal.
I recently bought a Bernina Q20 and was able to get "expo pricing" on it even though the expo in question was in another state. But they had a booth out there, so were able to give me the expo price on top of a sale price in the local store, and then I was able to wrangle a few "freebies" thrown in to the deal (assembly, delivery, and a ruler foot!). I didn't get half off (wow!), but I still have not seen the machine selling for that low of a price since then so I'm still very pleased with the deal I got. (And I adore the machine itself, that helps!)
