I have used that site for other products, but I was just curious. I guess I haven't tracked a product for so long before on Amazon. I used to search and buy on the spot, but these days I have to think it through a bit. Just surprised a simple thing like a keyboard goes up and down daily on price.
I just ordered this keyboard two days ago for 59.99, yesterday was 49.99, and today 79.99 and the mail-in rebate form for $20 is gone from amazon website. I also have a habit on ordering on spot, but had to order some tools. I put them in the cart, but waited couple of days to actually order (waiting for my paycheck to come in mail). This how I noticed the sudden and sometimes dramatic price changes on amazon. I use firefox, so I found camelcamelcamel.com addon to it. It save me some money so far. However, I also did not used it on this keyboard (on spot buy), just one day and I could save $10 on it. Still 59.99 is still below average of $63 as reported by camel and I will get $20 back with mail-in rebate. Best
their prices can fluctuate in a store too, but generally they are fixed on a tag, not changing hourly like on a computer.. basic laws say they can change every minute up to the point where they sell one, then it can't change again until tomorrow. simple info says people shop less on wednesday so price may be lower Wed than Friday when everyone has a paycheck.
Amazon also has the ability to track how often you view a product, If I knew you were coming back repeatedly to look at an item, or the item suddenly got way more hits than usual, I would assume sales will go up and so would my price. this is common practice with online retailers.
Amazon has to make money too, just like the rest of us. what you need to learn is how NOT to trigger price inflation on items you want. stop browsing it until you buy and if you do browse to watch price don't do it logged in! if you think you've found the bottom price, put it in your cart. I placed an inflatable boat in my cart at the low and the price stayed fixed for 4 weeks until i checked out. the day after I ordered it jumped 30%
As of June, 2013, you can get this at Staples (in store or online) or the Logitech Web site (and elsewhere, I'm sure) for $79.99. It's way overpriced at Amazon, probably because it's sold by a third-party vendor (and, the vendor seems to keep changing).
