My purchase of 3 new hats was documented as follows:

BERET + DERBY = TRADE.......code1
FEDORA + DERBY = TRADES...code2
FEDORA + BERET = TRENDS....code3

The short negations below will assist you in solving those alphametics:

code1: 246 is not good.
code2: 653 is not against.
code3: 609 is not beginning.
