Just came back from best buy 1 hour ago. Got PNY 8gb kit (two 4gb chips) for 45.76 cents including tax. Normally 60 dollars. Sale ends saturday he said. http://www.bestbuy.com/site/PNY+-+O...24&skuId=4816107&st=pny 4gb so-dimm&cp=1&lp=6 And even though the link doesn't show it mine had a picture of the mac symbol on it. So its meant for mac. Both on the shelf had the mac logo. So not bad. Running Apple Hardware Test to verify all is good. Will reply after its done.
