PersonalFinds the real lowest price for what you want to buy
Deal finder
Tell it what you want to buy and it checks the retailers you like and the ones worth knowing, then ranks the offers by the price you would really pay at your door, with returns and warranty side by side. It can watch a list of items and tell you only when a price moves enough to matter, and it says plainly whether to buy now or wait. It never buys anything unless you ask, and even then you confirm the final total yourself.

What it does
- Finds the same item at several shops and ranks them by delivered price, not sticker price
- Adds shipping, sales tax or VAT, import duties, card or currency fees and any codes that really apply
- Checks each shop's returns, warranty, stock and whether it is the authorised seller
- Says buy now or wait, from the price history it can find and the sales calendar
- Watches a list of items on weekdays and tells you only when a price crosses your target
- Fills a cart for you when you ask, and stops before payment so you confirm the total
