It's me again follow up on above Delta SADP-65KB.
I am not certain if he sold me just the part that includes the 'brick'- or the other half of the cord also- the receipt says '19 volt 65 watt power adapter'.
What do you think?

Hi, ilmbg...

I try to shop physical and on-line stores, including eBay and Amazon. While I normally have the time to wait for the item(s) to be shipped, if I'm in a crunch it's off to the store.

As I'm sure you've noted, prices can vary for the same item. The reasons vary as well, whether it's someone who just wants to get rid of it, or a high mark-up store.

Hope this helps,
:-)
