Lol ok so the last 3 comments tell me everything i need to know and my initial post was deleted i think it's clear to stay away from overclockers store and bias forum, thanks for making it quick and easy, i'll be sure to pass on what i've discovered thx for your time.
Bias? I went through your list.
One was free delivery on orders over £20 which could take up to a week. They are a giant logistics company with their own warehouses and drivers all over the UK so why it takes ~5 days to ship something... oh wait you can pay extra for quicker delivery.
Two offered free delivery over £50, not much use when the item I wanted on offer was £45. Pay an extra £4 for delivery or add a usb stick to get it over £50, might get that delivered sometime next week. One of those stores used a delivery service that is so unreliable you'd be lucky to get the order at all within the time frame.
One was a US based shop and wanted £17 on a £45 SSD to import from the US.
One wanted delivery starting from £5.48 for courier, it is possible to get free delivery if you post on a different forum with a minimum order amount, meet other forum rules criteria, but none of that is advertised on their shopping site.
One had cheap delivery from £1.99 per order but as soon as anything of value was added (£50 SSD) it went up to £6.95.
There was only one in your list that offered free home delivery without restriction which they could afford to do as their markup on their product takes into account it taking up retail space and not just warehouse space. Even though they advertise that their staff test the products it's not generally done for PC components and not really much help.
Being a member on here is more than free delivery, I've had more troubleshooting help than any large warehouse/shop could offer from other members, had great advice on what to buy and what products to avoid and this goes further than PC hardware. Try and ask on Amazon support why your motherboard is not POSTing and they'll issue you a returns label, deem it not faulty and charge you for the return, on here members will try to diagnose and fix your problem.
