1st u must find 1 7/11 shop which allow u to stand there trial n error for 2-3 hours...
2nd before u go to 7/11, try to figure out the feature pattern, such as only G1 prime n UM is pointing finger, but G1 prime is holding a gun.. etc ect, i suggest beginner try figure out easier charactor such as shockwave, SS(with cloud), Unicon...but when u grab the plastic bag 1 by 1, squeeze, hold it, clutch it, press it... u know hows the bag will looked like...
the cashier for sure will stare at you...
so, after u figure out 2 or 3 character, u pay money 1st la, open it... then continue, let them know u are going to spend rm200 to collect all 
try few times..n few shops. coz my record if u are lucky u can get all 24 robot heroes in 1 single shop within 2-3 hours...
but it is very tiring, after 30-45 mins, ur hand n leg will start feeling painful n paralysed but trust me, it is really worthy when u display all 24 robot heroes on ur table~

overprice or cheap, depend on situation. some AFA graded stuff can goes up to few k USD, and people still going for it. we have different product to meet different customer range. some they prefer affordable/cheaper price, and not so fussy about box/toy condition, grap it and terus play with it. some prefer prefect mint condition misb box/toy, and they willing to pay a bit more, coz to get a perfect mint condition box/toy is not so easy, maybe 1 out of 30pcs or even more. i am sure some people here, when they choosing a toy, they will look at the toy up and down, left and right, to find the perfect piece    furthermore, some toys oledi out of production, when we get from supplier, the price has been jack up d. so, even reissue is out, the price for that "particular" piece still maintain 

some item dun have to wait for 20 years to jack up the price, as soon as the stock sold out in the market, and still got high demand, the price will definitely goes up, and yea, thats toy industry for an example, fans project city commander, 1st released was RM260-RM300, now oledi shoot up to RM500+, can blaim who... few months ago i bought a bib universe nemesis prime (repaint big convoy) at RM280, but 4 years back, it was selling RM69.90 only + 20% discount at parkson, and i did not buy it during that time. but now i am happy with it bcoz i finally got the item i wanted for so long, and it is still within my budget (i also search through ebay) 

we do have early birds & special offer for customer, from 10-15%, for latest tf toy, you can always check my latest pre-order list (famitoy.blogspot.com). even some hot selling toys such as tf masterpiece, tfclub exclusive tf, we still try our best to maintain as cheap as possible to satisfy our customer. for gundam, some old stock we are still selling yen x0.03 to 0.033, only latest shipment (including some restock) is yen x0.035 to x0.038 (due to the increase of exchange rate).

beside, unlike some seller, claim a ko toy as a original toy, and still say its as good as original. if its original, i will tell u it is original, if its ko, i will say it is ko.
