Secondly, Is best denki Warranty 5 additional warranty can be trusted, any problem when call for service?
suggest you check with Best what they mean by "5 additional warranty"...
. 5 years warranty means you get standard 3 years Sony warranty + 2 years in-house warranty from Best Denki
. additional 5 years warranty means (in plain English) you have a total of 8 years warranty (3 years Sony warranty + 5 years in-house warranty from Best Denki)
NOTE!!!
whatever that's agreed verbally, get them to write down in BLACK-N-WHITE!!!
had a bad experience with reseller "C" becos we forgot to make sure the salesman's words are recorded in B&W. salesman say warranty is on-site but when item spoil, service staff say no on-site, if want need to pay separately. really felt cheated!
i called Sony Customer Information Centre (6544-86oo) the other day to ask about the 5 vs. 3 years warranty and why electrical resellers (e.g. HN, Best, Courts, etc) gives only 3 years. the customer service officer said the 5 years is a special privilege/benefit given to Sony centres for displaying/selling "only" Sony products while other resellers display/sell their direct competitors' products alongside. also, those centres are encouraged to sell their products at RRP instead of discounted pricing.
hmmm... Sony centre at Clementi West also sells other products leh. but i also notice that it brandish Sony brand at its main signboard and displays non-Sony stuffs at the rear corner, "hybrid" sales model... whahaha
