Even if it's an honest preorder, why would anyone PO something on Ebay... there are countless retailers you could choose for that.
i don't know. i think many online shops do sell on ebay as a side. ebay has much bigger exposure than a normal online shop. folks who aren't used to buying from online shops or not knowing where to ask questions regarding online shops may find it easier to buy off ebay.
also there might be coupons or other incentives that they prefer to order on ebay.
ebay protection is only 45days, it's barely enough to cover the delivery time for Sea shipments. they used to be more but they are now 45 days.
paypal has 180 days, that is 6 months, well most of the time it takes more time between preorder & release. if there's an issue you may lose the deposit.
it's no different from ordering from online shops unless you use credit card which you can charge back.
to make the cost lower, some shops prefer bank in or bank transfer or credit card because that paypal charge around 4-5% will add up the price. so unless you use credit cards you aren't really that protected either.
any news on the outcome on the Custom sections here? have they sorted out all the cancellations? i believe most orders are paid via paypal. do you feel safe ordering on Sideshow forum than ebay?
