This is a gaming hardware deal rather than software... :)
<span class="bold">Logitech G600 gaming mouse</span> regular price $79.99 on sale for $49.99 and pricematch-discounted to $42.49 or thereabouts through another retailer because I am The Price Negotiator(TM).
NCIX.com has the mouse on sale for $49.99
ONE DAY ONLY today:
http://www.ncix.com/products/?sku=74357&vpn=910-002864&manufacture=Logitech&promoid=1244 memoryexpress.com will pricematch NCIX.com and beat their price by 25% of the difference in price from their own price offer which is currently the regular price of $79.99 (I actually waited for a prior memoryexpress.com deal to end so I could get a bigger discount <evil grin>). This gives a price difference of $30, and 25% of that is $7.50.
Memoryexpress page on G600:
http://www.memoryexpress.com/Products/MX40364 Awesome pricematch guarantee:
http://www.memoryexpress.com/Policies/PriceProtection.cm.aspx So if you buy it from memoryexpress.com it will show as $79.99, but during your order read carefully and there is a field where you can do a pricematch and paste the URL to the competitor's pricing, paste the NCIX URL above there. When you go to one of the next screens look carefully for a comment field where you can put additional instructions and make sure to put in the comment box something along the lines of:
"Pricematch additional instructions: NCIX.com's special offer includes free shipping, please match that."
They will then match the free shipping also and you'll get an awesome $80 mouse for $42.49 plus tax with free shipping.
I ordered mine last week during a $64.99 sale at NCIX and pricematched it on memoryexpress.com who beat them at about $61 or so, but they also have a 7-day price guarantee so if the price drops in that 7 days they will update your discount on the pricematch and refund it to your account. I submitted my update request today and they tell me it should be processed by the end of the day.
This is a great deal on this awesome mouse! People who don't "get" why you'd want a mouse with 20 buttons need not apply, go back to using your 1 button Apple mouse. LOL
Anyhow, I couldn't not share this deal without feeling guilty so if anyone buys one let me know you got the deal so I feel good someone else benefitted from my share. :)
