When shopping online, whether on a major retailers site or on eBay, try this easy tip.
Firstly, make sure you set up an online account with the retailer. This is normally just a case of entering your details and an email address. Confirm your email address and ensure that you are logged in.
The next step is easy, just go browsing through the products you are interested in, and add any items you like to your basket. This works the same on eBay, do not use buy it now, just add to your basket. Then simply leave the site without completing the purchase.
Some sites will give an immediate pop up offering a discount (normally 5-10%) to encourage you to complete your purchase. Other sites and eBay will send an email after a couple of days with a discount or from eBay saying you were interested in this item at £x it has now been reduced to £y.
It won't work on every site, but if you are not in a hurry to purchase it is worth a try.
