They seem to run sales as often as Macy's.  I couldn't tell you timing, but when I was looking last year, my A3 was on sale more often than not.  Maybe their anniversary had something to do with that?  If you're really interested, try calling a rep and see if they will give you the sale price you have seen.  Otherwise hang tight and check back every few weeks. 

Yes, the sales are often, but never when you are ready. I have found them pretty intractable about price between the sale. I once had them quote me a price then refuse to honor it a few weeks later because the sale was over, and the reason it was a few weeks later is because the rep didn't return my calls or emails to get a few questions answered.

Usually you have to order then wait a few months for a shipment from Europe. Occasionally they will order several extra machines in anticipation of demand, then have a sale to clear them out if the demand wasn't there.

Best thing is to just call and find out if they know what's coming up - but definitely wait and don't pay retail because it WILL go on sale sometime this year.

When I was researching prices from a competitor on a bandsaw, I did find there was a pattern of sale prices available in the fall.  If Hammer had their sites set on preserving or gaining marketshare, they would have to match pace and load up with inventory around the fall and try to move it pre-holidays.  So worse comes to worse, if no other opportunities present themselves, you'll get a chance around Sept/Oct.
