I bought one in Netherlands.

Currently local DIY has a discount of 20% on pretty everything. They sell the bags at a regular price of € 39,99 so with the discount it would be € 32 (approx. $ 39,50 at the current rate of exchange).

I took a quick look at DHL side for shipping cost to US. Parcel up to 4 lbs is approx. € 13 (approx. $ 16).

If anybody is interested then plesae let me know.
