20% + 10% is slightly higher than 30%. Imagine you take 30% from RM1,000.00 is RM300.00. But 20% + 10% is 1st you add 20% to your RM1,000.00 which totalled up to RM1,200.00 then and then only you add the other 10% which is RM120.00. So your taxable total is RM320.00

Unfortunately the issue here is that all Sideshow statues are made from Polystone and not porcelain as described in Sideshow web;

"Polystone is a compound made up largely of polyurethane resin mixed with powdered stone additives that give it added weight and the porcelain or "stone-like" feel that resulted in the materials name itself. Polystone is durable and highly effective at maintaining a sharp paint finish. Unlike porcelain which is fired in an oven, Polystone is a cold-cast material in which no heat is used in the manufacturing process, resulting in much greater variations of paint finish".
