I've been monitoring RAM prices on Ebuyer ever since the Google Checkout promotion started, and 1GB of this type of RAM used to sell for around £39 incl VAT.
Now going for only £30 incl VAT. Just placed my order! Came up to £33+ including supersaver delivery, and after the Google Checkout discount only £23.01!!! Bargain price for a 1GB stick of this RAM.
Note for Apple users: Fits all MacBook, MacBook Pros, Mac Minis, and I believe iMacs too. Its also the higher 667Mhz version instead of inferior 555 or 400+Mhz ones!
At last time of checking, only 5 available! Although I expect eBuyer to have more stock around.
Now out of stock. But keep checking! eBuyer usually refreshes their stock often.
