keep in mind the "collection" package's are still sometimes more bang for your buck. take for instance the Glass Cleaner collection:
you could buy the BOGO Glass Cleaner for $34 after discounts.
or
you could buy the glass cleaner collection for $43 and get the same BOGO content plus 2 glass towels and a funnel for an extra 9 bucks. and can't all of us use more glass towels and funnels, at least I can hahaha.
