I am relative new to this site, and thanks for this great site. When that is mentioned, I am really missing some data mining features. As this site only focus on amazon, it only gives a narrow perspective to the prices in other stores. You know, amazon isn't always the cheapest... :)
Therefore I suggest Brickset to look into fx, pricerunner for price comparing up front to amazon, or local 2nd hand sites like dba.dk or ebay. With the pricerunner example it is comparing local stores prices and gives a list of prices where you are able to sort them with or without shipping and some more.
If this is the wrong forum to ask please direct me to the persons/groups that is the right ones.
Thanks for making my lego even a better experience than before I found BS...
