Looking to buy a Macbook. Should I buy a few day old one with no receipt for $1370 (probably not going to buy it). I thinking of buy one from Amazon or Macconection. but not sure when either will have them in stock. Also does anybody know if I order it on MacConnection is the rebate vaid if i get the Macbook at the end of june? Rebate expires may 31, says send it in within 3 weeks.
