In Boothbay Harbor check out the store "Istana" at 49 Commercial street, they have fantastic gifts, home decor, clothes, bags, sculptures, many, many unusual items, one of a kinds, and at fantastic prices. Also a great fishing town to visit.
Into antiquing? There are a bunch of flea markets in the area, and of course antique stores. Great bargains can be found at a place called Ed's Stuff. If you're coming from Boothbay Harbor, he is on Rte. 1, just before the bridge to Bath. The store is a mess, but his prices are better than any of those places where you can easily navigate through the aisles.
For clothing bargains, go to Renys. The one in Bath has a nice selection of quality merchandise, including brand names, for prices that will make your jaw drop.
