Show HN: I made a site that calculates the market price of items on ebay

This was my weekend project. I made it after being frustrated at not knowing what a fair price for an iphone 5 would be on eBay. I posted this a month ago but wasn't ready for HN traffic. Learnt about load testing the hard way and have optimized it since. So, here it is again.<p>Feel free delve into any questions.

The search term "win&#38;win riser" breaks it. Looks like you're not url-escaping the search term?<p>EDIT - also it looks like you're submitting it to ebay badly, the results for "win&#38;win" are same as for "win".

This is a really nice little app. I mean I have only used ebay only a couple of times but this is really nice, and its something I kinda wish I had at the back of my mind when using ebay.<p>Can you give a little details on how it works? Is it scraped data? etc.<p>I know this is targeted at a person who wants to sell items on ebay, but I am a buyer and I find this still quite useful. Not sure how up to date the data is but the graphs are an amazing feature! Makes so much sense.

Bug report: choosing US, UK or AUS from the country select dropdown causes the form to submit as if you'd typed in the country code as your search term.<p>This is a really killer piece of kit though. I'm very impressed. It's something I think many of us have idly imagined when struggling to determine a good starting price for a new eBay auction.

Very neat site. I think overtime, you should try to find more visually pleasing ways of presenting the data, but for now it's not a deal breaker.<p>I have a suggestion: Perhaps you could build some kind of e-mail alert system that lets me know when there's an e-bay "Buy Now" item available within a user specified price range. You could also let me know if there an item I want is still within a certain price range hours before the bid closes.<p>EDIT: Typos.

Suggestion: You should be able to exclude certain data items from the calculation, then recalculate (check box for exclude next to the raw data item or something). I just did a search for "fender aerodyne bass guitar" and the lowest price that came up was $249.99, though that turned out to be only the neck of a bass "2007 Fender Aerodyne JAZZ BASS NECK Tuners Bass Guitar Black Headstock".

Looks awesome! Some outlier elimination would be great (on a search for a graphics card there was skew due to unrelated items)

Dude, put a contact link on your site so people can give feedback. Also, once someone does a search, you should pass the search query into the search box so they can make modifications without retyping the whole thing.

Is there any way to search for a certain condition only? When I search for the iPhone for example, it returns a huge range of prices that include ones that were used and refurbished.<p>Otherwise, it looks like a great site!

Nice site, but I would like a third graph which shows (e.g.) the average price (for the day) in the y-axis and days in x-axis, so you can estimate how the price has developed over the last few weeks.

Great job, in addition to the comments already made I think it would be more useful if it said what you would make from a sale after ebay and paypal take their cut from the sale.

Nice site! Could you please add more countries? Spain (ebay.es)?

Possible bug report: I searched for "thunderbolt LCD" and [recently ended graph] doesn't seem to match up with prices in [recently ended table].

Clever idea, it's always time consuming to explain to my father in law that he'd be better off buying something new in the shop or online.

Looks great and could be a very handy tool but I would of expected prices to show up in £ rather than $ when selecting UK.

Small bug, searching for "2012/13 Panini Elite Basketball Hobby Box" confuses your URL pattern, only searching for "2012"

seems to break when i put in a specific season, ex:<p>- "dexter season 6" returns only listings where season 1-6 are sold setting an average price at ~$140 - "simpsons season 9" returns listings where multiple seasons including season 9 are sold setting the an average price at ~$150<p>In each case the 'raw data' had more than one season in it

Ah, that comes very handy! Thanks.<p>Would it be possible to show the full link when hovering over a truncated link ("lin...")?

This is great, very impressive. When searching for an item in the UK the price still shows in dollars.

I tried to search for a speedmaster 3510.50 and it cut off everything after the period. Regex issue?

Just curious: this is not in line w/ebay's T&#38;C, or is it? Quite impressive, anyways.
