Is the shami-shop reliable?

I ordered a few strings two days ago and I’m worried about it was just a scam an I spent 17.5€ on nothing.
Or wose I’ll lose all my currency on my card.

You don’t need to worry.
Shami-shop is one of the most reliable shops in the EU zone.
If you search the forum here, or ask our members in the Bachido Discord server, you will only hear good things about it.
