I was referring to links that don't get updated, they become misinformed and misrepresentations. For example if links are posted outside of the OP, in 4 months they STILL read "x power supply for $y", even though that psu could be 5x more, 5x less, not sold at that site, at all or recalled due to being dangerous. The OP will be updated so doesn't suffer from that problem.
That's an assumption you've made. That my post won't be updated.
So far, it is. Let's keep the assumptions to a minimum.
At this point it's more updated than the OP is. The CX430 is on sale for half what you have listed in the OP.
That's a 67% difference if I am doing the MATHS right.
A spot price is guaranteed to be right, potentially for the whole period before another update is done. Again, people buy from spot prices not trend data.
By your own admission, Amazon pricing can be very volatile.
Case in point? Of the 67 supplies listed in the OP as of this moment, 37 of the prices are incorrect. Some are grossly incorrect.
What's more is it's tapping into a single source of data for pricing.
So... guaranteed to be right?
Guaranteed? No. I'll disagree there. Sorry. You can't have it both ways. You can't say spot pricing is guaranteed and then say Amazon is too volatile for you to keep up to date accurate pricing information.
Educated buyers - which I hope we all are or hope to become -
shop for things before buying.
They compare prices.
They want to know how things were priced recently. Am I getting a good deal here? Oh, the average is $40, and the low was $25. So at $30 I'm in the "Good Buy" range. At worst, your OP should link to CamelCamelCamel so that people could see that data for themselves, even if you won't provide it outright.
What's worse is you ARE BASING YOUR SCORE off this incorrect data. And then people are making decisions from that.
Do remember that each additional piece of variable data you add, increases the time taken to update the list. Ie we only have about 40 PSUs at the moment. If that ends up at 100, thats 2.5x as long.
Then if you add average and hi low pricing, as well as 2 store links, thats a further 5x information that requires updating. There becomes a point where its not viable to run with so much variable data because people will buy or not regardless of $5 variations of what we've listed the price at.
You're working harder. Not smarter. And we're talking significant differences between the prices you're linking to and what the average street price AND sales price is.
I've already started throwing some of this data into spreadsheet that spits back forum bb code in one copy/paste. It has the ability to capture multiple pricing points and create some metrics off that.
A db aggregating more data would be the next logical stop.
