I went to Millets for a decent tent last year during festival season. I was impressed with the help I was given there as I didn’t have a clue what was good/how to actually put up a tent. A guy went round the shop with me talking about all the different tents and then when I chose one he actually showed me how to put it up in the shop! It was quite pricey but I think that’s just the going rate for a decent tent that actually survives rain and wind! And I will be able to use it for years.
