Oxford and gingham shirts
I have many shirts in oxford cloth, here are the usual prices I have seen them at:
Oxford Shirts (by price)
Uniqlo: 34.90, offer at 19.90
Timberland: 60-70 on offer
Marks and Spencer: 69
Brooks Brothers: 90+
Polo Ralph Lauren: 120-160
J Press: 170 (pitiful discount sometimes)
Some other outlets like A&F, banana republic, departmental store brands but I think their cuts are too modern for my liking.
If you are looking at a formal shirt, Marks and Spencer produces the best quality at the lowest price. If you are looking for casual, Uniqlo has the cheapest shirt but the ironing is very difficult.
Gingham can be found at these brands or retailers too, but I don't keep note of the price
