I love it when I sit down at my desk in the morning and find something useful waiting for me in my inbox. Such was the case this morning. Yesterday I mentioned a site that compiled a lengthy list of Web sites designed to find travel deals and discounts.

Here is another site that offers a list of 50 places to go - other than Craigslist - to buy, sell, rent, trade or find services.

Among them:

Find a Dogwalker: Don’t let your furry friend have to hold it all day long. Find a friendly dog walker in your area through the listings on this site.

TextSwap: Textbooks can be a big expense for college students, especially for those with less than deep pockets. You can save a few bucks by trading your old textbooks for new books you need on this site.

BuyOnIt: This auction site has listings for items that range from the bizarre and tacky to used cars and motorcycles.

ApartmentRatings: This site not only lets you search for apartments in your area but can also give you other renter’s impressions of the properties and their management.

Blurbpage: Simply choose the area that’s closest to you and start browsing through these ads, which contain listings for community activities, jobs, buying and selling, renting and more.
