'goods' is the definition.
(merchandise is a kind of goods)

'german wheels out danish electronic' is the wordplay.
'german wheels' becomes 'merc' (I can't justify this - if you can you should believe this answer much more).
'out' indicates anagramming the letters.
'electronic' becomes 'e' (as in e-mail or e-books).
'danish' anagrammed gives 'handis'.
'merc'+'handis'+'e'='MERCHANDISE'
