In addition a page to cover some basic deal-search questions that I put up the other day, I just finished up two writings on shopping tips: Buy a Mac & Ways to Save Money Online. For each, I broke up tips within the topic and explained each tip a bit with a paragraph or two. These tips are what I as a consumer would consider helpful and practical. Take a look at these shopping tips and drop a comment to this post. I sure can use your tip too to touch them up and/or write more tips based on your inputs.
For other money saving tips, forums at SavingAdvice managed by Jeffery Strain and Nate Sanden also worth your visit. The collection of their Personal Finance Blogs give insights to others' daily money saving life.
