**** Are there any sales?

There aren't any sales, holiday or otherwise. That's because I see consistent pricing as a form of transparency with my customers, and notes that items are already competitively marked as a primarily direct to consumer brand.

**** Do you offer free shipping?

There is no such thing as Free shipping. If you want to deliver something long distance from A to B, you have to pay for it. Companies that offer free shipping include postage in the price of the item.
I found that it is more worthwhile for my customers to calculate the postage later, on the total amount of goods in the cart.
Postage for 1-2 products is around 10-12 euros.
