When collecting any TF figure, you come across deals online that fit into your price range, but are either minor incomplete of severely incomplete. If you went ahead in purchasing said Incomplete Transformer, you have a mission on your hands. Track down the missing pieces. Now you think to yourself "Ive got to find all these missing pieces so that "Insert Transformer here" is complete". So say it takes you perhaps a week or 2 to finally track down all your missing pieces for the TF and there you have, a complete figure, but was it worth it? For a somewhat more amount of money you originally started with, you could have bought the complete version if you had the money, but you decided that based on your amount of $$ at your disposal, you can either choose to buy an incomplete figure and track down all the pieces you need or save up for a few more weeks or so to get the complete version of the TF that you were intending to buy. Fact of the matter is, which do you think is the cheaper choice to when buying a Transformer? Buy the incomplete version and take a while to find all the needed pieces at possibly a cheaper price than buying it complete on the first purchase or to buy the complete version since collecting the individual pieces could cost more than buying the complete version.
