Decathlon is an excellent shop with a very good product range in sports. Much better than mist of its competitors. The biggest differentiator for me is the customer service. it is quick, efficient and helpful. I chose "Good" in overall rating because sometimes the pricing is not as competitive as it should be. For instance, next to your Oxford branch there is Sports Direct and most of the times I can find the same kind of product cheaper in there. I do not want to be too harsh because in general Decathlon's product quality is much better then SD (for instance bikes etc.) but when it comes to clothing I cannot notice a big quality difference. I hope my feedback helps.
