Yeah i also feel that fault is mine, but please don't glorify Reputed sellers, i found on this forum that many reputed sellers have also bad history and many buyers are crying after deceiving by them even ebay don't take any stringent action again them, most of the time ebay award cases in favor of them because they have Thousands of feedback, most of the time these sellers sell their stuffs as much higher prices than local market.
Most of the time new seller with low feedback are selling their stuffs on Affordable prices to gain customers satisfaction, you can find most of the item i purchased are from small seller, even i can
say that its nothing to do with Reputed or small seller but ebay's some policies, those are unnecessarily illogical.
Like in my case i am going to wait for 15 days without any reason, even seller has confirmed that he is not going to ship and i also shown my interest for refund (I did it because ebay don't have any policy or method to force Seller to ship this order even in India as per Indian Contract Act 1872, Buyer is eligible for compensation in such type of cases, but ebay is not able to protect buyer's interests and rights)
Anyway i was looking for some Old computer parts hence placed my bid as your "reputed seller" don't sell old items.
Now i feel that its not the fault of seller but its ebay who don't have any system to safeguard us in such situations.
