I bought 2 bottles of Olmeca Altos Tequila from Mybottleshop.com.au after I found they were the only company who supplied what I was looking for. After seeing reviews I was skeptical but in the end very pleasantly surprised.
Their customer service was fast and friendly, their products arrived promptly, well packed and in general, the experience was very decent.
I'm unsure if they've had some restructuring in the past few months to increase their service but I wouldn't hesitate to order from them again.
Many thanks especially to Amy, who was incredibly helpful on my inquiries.
