Being new in collecting toys way back in the 90s, I was easily influenced by others. One evening, I was at Sogo looking at these Voltron 3D figures by Trendmaster, I was 'prompted' to buy the figures by a 'passing by' collector. He said, "Get the girl, its rarer of the lot". So I got the girl. But you know, being a toy collector, once you have one figure, you would like to collect the whole set. So I got all the figures. When I reached home, kinda regret. It was impulse buying. Duh! Try to sell, nobody wants. Duh again! Good news is - I'll reserve this set for my future toy museum.
1) Never buy toys on impulse
2) Never buy toys because someone ask you to, buy because you like it.
