Affiliate Marketing Secrets

I have built my website, which is http://apple-store-usa.com/ as an amazon affiliate and they sign me up for CbProAds. At first it all sounds good but then they start sending me email to upgrade or become a lifetime member. I don’t really know what to make of this. Should I upgrade? Are they gonna charge me more?

Right now, I’m using a Micro Four Thirds camera called Olympus Pen PL2 (with a kit lens and a 45-150mm zoom lens) I’m pretty happy with the image quality right now but I’m thinking about upgrading for the greater range of advance features/option/controls and lens availability. However, I don’t plan on getting that many lenses in the foreseeable future in order to consider the D90’s internal AF motor over the D5100.
Along with this, I’m buying the cameras used. I could get the D5100’s body and kit lens, or get a D90’s body and about 100$ for another lens.
At the end of the day, I just want greater ranges of control and IQ improvements on the side. Which one should I consider? (My budget is stretched to about 500$. Please don’t suggest getting a D7000, which is out of my budget-range)

I want to upgrade my brother’s pc and he has the Kingston / KVR667D2N5/1G in his pc. Same as the one on this link.

My question is, if I want to upgrade the ram, can I use the 2gb like this link http://www.misco.co.uk/Product/Q128088/Kingston-ValueRam-2GB-PC6400-DDR2-RAM or http://www.misco.co.uk/Product/Q74932/Kingston-ValueRam-2GB-PC5300-DDR2-RAM
The 2gb ones on the link, are there difference with them both? or not?
What would you suggest?

I went from Windows XP since it came out to Windows 8 on Tuesday. I’ve lost files in the upgrade. I don’t know why things are doing what they do, windows moving around when I don’t want them to, changing size, can’t find anything, my games don’t run, Quick Launch is gone, my internet shows disconnected even though I’m online but apps on the apps page won’t connect and thus won’t run.

I joined Zeek Rewards as a silver and have qualified for matrix commissions and my back office shows I have 160 affiliates in my down line. Am I losing money by not upgrading to the Gold or Diamond level?
