Newbie question because I only sell a few items on my website and they are all via Pay pal single item shopping cart.
Background is that I aim to sell all items cheaper than anyone on Amazon and Ebay. I adjust the prices up or down to ensure I am always the cheapest by a few pence.
The other day a major competitor backed out selling at their low price and I was able to increase the price of one of my items by £4 on my site (and Ebay as well) still remaining the cheapest.
24 hours later I get and order for 5 of the items at the previously lower price (via my website). I assumed at first that the purchaser used a cached version of my page to make the order but he tells me he ordered the item on his mobile using Firefox.
Can Firefox use pages 24+ hours out of date for something like that? Any thoughts?

Pages are frequently cached in hubs to speed up load times. To help avoid it, you can use no-cache tags in the <head>. <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="expires" content="Mon, 22 Jul 2002 11:12:01 GMT"> <!-- meta http-equiv="expires" not fully recognized --> <meta name="robots" content="noarchive" > <meta name="googlebot" content="noarchive" >
If you are using asp: <% Response.CacheControl = "no-cache" %> <% Response.AddHeader "Pragma", "no-cache" %> <% Response.Expires = -1 %>

How do you get from A to B? That is, how does "mobile + Firefox" translate to "can't have been cached"? Caching doesn't only happen within a physical browser. It can be done at several points in transit, including the user's ISP.
The important thing is that the server doesn't know a particular page should not be cached-- unless you tell it. And then you have to hope the ISP pays attention to this directive. (I trust the browser more than the ISP in this regard.)

One of the local ISPs is notorious for caching everything in sight-- up to and including login pages with all boxes filled in. Apparently if you're enrolled in the higher price ranges they are more likely to serve you fresh pages.
