Bump - Dude thanks!! This is going to come in real handy.
I just got back from Europe and decided I DEFINITELY need a 13" laptop with long battery life. Way too much traveling coming up.
With stuff that has "specs" I'm a huge fan. Congrats on a job well done so far.
That said, if anyone has a recommendation on a 13" laptop to compare with this, I'm all ears. Just started researching..
Thanks

I'm hoping that eventually (much later, after the site works completely) I'm going to have something in place that helps with finding products to compare as well as comparing the products. So then not only will I be able to compare products, but I'll be able to recommend you products to compare (basically getting Which Product more and more involved in how you decide which product to buy so I can attract people at all stages of the buying process).
I like it, grand idea old chap. Perhaps if there are no common specs to compare for 2 items i.e ford explorer vs apple ipad, show a message that says 'sorry we cant make that comparison' or something instead of just showing the 2 products and blank fields underneath.
Also curious if each comparison gets saved as a static page? might that help for the serps? like if someone searches apple iphone vs htc diamond that page could be saved under a category "phones" and then indexed by google.
I'm so smart sometimes it hurts... it's amazing I pretty much make no money
The error message is a good idea. I can still get the Amazon review and Customer rating and compare those, but just giving a message telling users what's going on seems like a good idea. Most of the feedback I've been receiving is about making it more clear as to what is actually going on... and it's something I'm going to spend a lot of time working on now.
And yes, each search is pretty much saved as a static page.
You need to put in the exact model numbers in the Amazon title for it to work well. Otherwise I'm sure it needs to find a way to guess.
For products that have two different "versions" (such as shoes that have multiple sizes and colors), it also doesn't work that well. A few laptops were showing up like this. Amazon's API SUCKS for these kinds of multiple-property products, and it drives me nuts because the API should really be better. I'm assuming that's what cardine's run into as well.
Yeah that's almost exactly my issue (search Motorola Droid on Amazon, which pretty much sums up those problems).
I realize this is tough as it's using Amazon search. But the results need to be improved before I can see anyone using it. Maybe when the "Did you mean" boxes pop up, you could show a thumbnail of the product next to each item as well as the price? That way I could select the phone as opposed to the case (as I know the phone is more expensive).
That's the best idea I've heard so far as to how to combat this issue.
Another idea I just thought of (based on your input) is when recommending products, show them the Amazon title of the product. For instance if one of the recommended searches is Droid X, instead of saying 'Droid X' it will say 'Motorola DROID Multimedia Docking Station' since that is the result that Amazon will find when it actually does the search. That way it is a lot less confusing and the user won't be surprised that they get a different result from what they were intending on searching.
Also I just got an SQL error-
Could not insert data because: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's Laboratory: Mandark's Lab? (PlayStation) - Compare prices, reviews, user opini' at line 1
What were you searching when you got that error?
Also since from my logs it looks like half the failed comparisons are for cars, I'll work on adding a car comparison feature.
Thanks everyone for the support and feedback. Most of my good improvements have come from negative responses, so keep the criticism coming
