Shopping, including tea bags (9)
I believe the answer is:
purchases
'shopping' is the definition.
'including tea bags' is the wordplay.
'including' indicates putting letters inside.
'tea' becomes 'cha' (cha is a type of tea).
'bags' becomes 'purses' ('purse' can be a synonym of 'bag').
'cha' going within 'purses' is 'PURCHASES'.
(Another definition for purchases that I've seen is " commodities".)
