Yes, and I don't think it is fair.
2 days ago you could buy the S1 Pro for €599 (without battery). Today you can only buy it for €655 (without battery!).
If you want the unit with battery, you'll have to wait until their stock (without battery) ends. Then they will start sending the S1 Pro with the included battery. But... as you can imagine, they will probably sell it for €655, instead of €599. (that is, if they don't increase the price again...).
I've been following the S1 opinions and forums since April, when I found this unit at a venue.
So I pretty much know every price at every store since April, as I wanted (note: "wantED") to buy two of these units in the end of this month. I can tell you that store is not the only one playing with prices increase...
Thomann is not the only one to act like that. The well known Gear4music, increased the S1 price this week from £529 to £600! Or, ir you think $, from $712 to $807!!! Or in €, from €600 to €680!
So... I'll never buy the 2 units I wanted to buy.
Lucky those who live in the USA. I wish I lived there.
