I see at other HD's they have some items on clearance i was wondering if manchester HD would match the clarence of other locations?

Yes they HD prices at every store if in stock. I would also ask if they price match.

Correct. Cathy at the hooksett HD is a real loser. Stay clear from her. She would raise the price if anything. Oh she is an absolute nightmare

Yes they will honor the prices at every HD if it is in stock

They do have many items clearance. It is possible as corporate dictates discounts that they could be the same item selection.
