You didn\'t save much with the mega paint set (and yes you did save a little bit, I did the math. Plus you got the handy army case with it, $50 value), but with international shipping added I can\'t imagine it would be worth it. I\'d just buy the colors individually. Besides, if you already have the core selection plus a few doubles, it would be cheaper just to buy the rest.
To avoid buying doubles I have an inventory sheet (I buy enough paints that it\'s worth it! lol) Write up a list of what paints you have. Might want to alphabetize that list to help keep things organized. When you discover that one of your paints is running low, make a check mark next to it, that way you know to buy another pot of that color the next time you go to your GW store.
I\'d recommend that you go to the GW website and print off a list of all the paints. Go through your paint collection and check off each one you own, then take that list to your GW store, so you\'ll know which paints you need to finish off your set and not risk accidentally buying doubles.
