Okay, this is the trick. Find out which features you need and what is essential to you when buying an item online. More importantly, work out what you DON'T need.
Say that I need to buy a new phone:
I DON'T NEED:
A flip/swivel head that is likely to break rendering my phone useless
I DO NEED:
One button speaker phone
A built-in torch (very handy for illuminating the back of the TV and computer)
You can save yourself a lot of time and effort if you cut out the features you don't need. From there you can move on to getting the best price for the item.
If you get caught up in features and extras and all that sort of thing, you could be shopping forever.
1. Find out what you need
2. Find out what you don't need
3. Narrow it down and get the best price
