Something like that happend the me too :-( when i went to buy a red axe , the only one at the fair of wonders was the lev 3 killer axe... I didnt know that i had to wait to buy the Big killer axe.... i am lev 8 and i was needed the Big killer axe , but when i saw i can only buy the level 3 killer axe i bought it cause i thought it was the only axe i could buy, now can i give my killer axe (30 gold) plus 6 more and buy the proper axe for my level ? If not then it was a "trap" for me , and i wonde...
