wel being a Experienced Buyer from Bazee let me tell u few tips
1st Buy only from Super Sellers or Who have 98-99% Positive Ratings.
2nd Bazee provides Security for both Buyers and Sellers ..so if Some thing Goes wrong..eg, the CPU does not work etc etc ..u can immidetly contact the seller OR Bazee and in the Rating Field give a Negative rating .
3rd Give a Ac Payee Cheque or Draft only
4th As world is not Perfect so is Bazee so Just Keep your Fingures Crossed till ur Transaction is Complete ..
