I buy the cheapest Jersey I can find on sale, I don't buy the cheapest shorts I can find but I do wait till they're on sale.
I haven't tried these shorts yet, but Amazon sells one called the Sponeed for around $40 and it gets very high reviews from over 3,000 people. Most of the time I get Aero Tech shorts, but again only when they have a sale.
I also buy the cheapest socks I can get on sale.
But I don't mind spending $100 plus for shoes.
I always look for closeout deals because that's when prices are reduced the most.
