Raise my prices?

I was at Lowe's yesterday nosing about in the window covering dept. I asked the sales person about some shutters. She told me the price for a 60x60. $909 for a Graber wood shutter. I sell that same shutters for $525 and I get it the customer 7-10 days faster. When I asked how much that was a sq foot she didn't know how to do the math! As I did the math for her, her co worker asked me if i wanted a job! I checked their prices on 2 in faux wood and real wood from Bali. A 60x60 faux was $175 I sell it for $135 and the real wood was $217 and I sell it for $175. I offer Free measuring and Installation and Lowes charges a whole lot of money to measure and much more to install. I think I need to raise my prices! Don't worry I wont. I may lose money on every job but I make it up in volume! God just keeps my phone ringing.
