Youre talking about the same retailer that generated its own hate fansite Suprastorescam.com (since closed)
I have never heard of an online retailer staying in business as long as they have considering their appalling reputation.
I have sourced many parts through both Suprastore and MVP. I will never EVER use Suprastore again, unless forced by gunpoint. The difference in Customer Service between the two are just in entirely different leagues.
Here's a short on my Suprastore experiences:
Ok, 1st hand experience of Suprastore pretty much confirms what most have said. I have sourced about 90% of my materials through them, only due to the fact I am American and have a little shipping deal to avoid Import Taxes.
I basically spread most of everything across 3 orders. The worst experience was the Apexi S-AFCII, which they claimed was in stock. The common bits were shipped within the week, but the AFC wasnt included. When I phoned them up, they said they were due in the next week. A little frustrated, but hey... 1 week right? Well, 5 weeks later they finally confirm it shipped out to me. Other orders were also broken into different shipments as they arrived in stock to Suprastore varying from 1-3 weeks + delivery time to the UK. Most phone conversations to customer service left me with no answers to ETAs on shipments! Mindful that everything was promised "in stock" while they were busy charging my american Credit Card.
If youre looking to purchase through a US supplier, go with Dusty at MVP. There is simply no contest.
