Very mixed feelings for me. I was in Leicester visiting a friend last year and on the way back home I took a detour to visit the shop. Nice layout with the pistols and smaller accessories in the front with the till then then assault rifles, LMGs, sniper rifles, bulkier accessories, etc were in the back. The bloke manning the shop was quite friendly and helpful. They had a few Deadly Customs clearance items so I bought those as I was genuinely in the market for them.
Earlier this year, I ordered online but they called me and were transparent about making a balls up on their stocktaking so they did an upgrade FOC. I wanted it promptly but didn't need it urgently though I paid for next day delivery on Saturday expecting a Tuesday delivery as I'd made the order in the afternoon but it wasn't delivered until the Tuesday after that. Not impressed with the delay whatsoever and I'd be reluctant to order online again from them.
I couldn't agree more with the sentiment above. I want just about every airsoft retailer do well, especially when they have a physical store but Extreme Airsoft really needs to up its game with its online retail operations.
