Balancing cost and quality can be tricky, but with a little persistence and the right starting points you have a good chance of coming out far ahead of what you would spend shopping in a physical retail store.
1). Online Marketplaces. These are great because of the mass of competition they bring. Examples include eBay, Amazon, and other large scale websites where numerous sellers can list products which are all searchable at once. With everyone trying to undercut everyone else the prices naturally fall. However, often those with the lowest quality product can afford to sell them cheapest of all, and because of the small order size it can be hard to track down the culprit and warn future shoppers off. Always check reviews for anyone you buy from online.
2). Large website retailers. These are great because they have an established presence which they need to back up with quality products. They also focus on large orders and holiday or anniversary sales, so be especially on the lookout for those. However, shipping costs and other details can tend to bump up the price a lot as you head to checkout, so be aware.
