Google Shopping brings up a list of retailers when you search for a product so you can see who sells it cheapest.
Ebay is also offering price matching on offer 50,000 items for deals through Cyber Monday.
The Slick Deals app has user vetted deals from other savvy shoppers to highlight products you might have missed.
Don't forget to look for coupons or discount codes.
A browser extension, like Honey, automatically applies any codes at checkout and has a price tracker built in.
Also, make sure to check the retailer's social media for special codes or advanced notice of sales.

It's not much of a deal if you end up having to pay for a retailer to restock an item or for postage if you return it.
