Hey, I'm interested in buying, but these guys
https://bitcointalk.org/index.php?topic=508904.0 Minereu.com are based in UK and their price comes out at about 1620 for 1 set of 10 units, but your price is nearly 400 higher than that for the same basic unit. Even with the shipping, Minereu is going to be 300 cheaper than yours, and as they ship from UK, there's no additional tax or anything.
There's quite a price difference here at the end, and there doesn't seem to be any reasonable reason why. Britain's VAT is only 3% lower than Portugal's, so that's not the difference, at best that's maybe 50?
Your full package is an advantage over Minereu.com at the moment as they only sell the individual units, where as you offer the option of selling everything you need for an extra 100, but they have mentioned they will also soon be doing the same, so I'm not sure what the advantage is.
If you can price-match these guys, or explain to me if there is something else I'm missing as to why Minereu.com is not actually cheaper (I see no difference as an EU resident, the only potential difference I see maybe your shipping fees are cheaper), then I would happily buy from you guys.
