Yes! You should not only expect to haggle, you're expected to do so! For example, I went to a dealer looking for the Brother Dream Weaver VQ3000. He showed me his price sheet with the MSRP price of 5995 and the store price of 4795. I said I could get it much cheaper from another source (as it turned out that source and online shop that a lot of people use quoted me an incorrect price of 3000). When I told the dealer the price he said if I could get it for that price, he'd order some too as he couldn't get the machine bulk wholesale for that. (Later I called the store and they had told me to "come on down" the day before when the gave me the low price- now when I questioned it, they said, oh, they must have made a mistake- Anyway the dealer said that the lowest he could go was 4000. While at the store I fell in love with a higher priced model (how did that happen
) and the MSRP was 8399, store price was 6695, and after a lot of going round and wondering if I could afford it, he offered it for 5300.
I learned my lesson the hard way. When I was much younger I went into a sewing store and bought a machine at the price listed on it. Can't remember if it was the MSRP but probably. Never thought to ask for a lower price or "extras". Now I know better. The stores certainly can't give the machines away but there does seem to be a lot of wiggle room at some shops. You can also get very good deals (so I've heard but not done this) at quilt shows.
I have to add that I think this goes for the higher end machines. I'm not sure if there is a built in margin on lower end machines and doubt you could go into a big box store and get a lower price but I'm not sure.
Forgot to add: if a store doesn't give a lower price they will probably give you extras and sometimes you can get both. Before you go in you should try to find out all you can about the brands that are available in your area and keep an open mind. You may like a machine once you've tested it or you may not. I read everything I could on all the machines that were in my price range/available range here, on Pattern Review, and blogs. Even though I'm fairly sold on this machine I will go to other dealers and try other machines before I buy. Sometimes you can buy a machine without trying it out (like the Juki 98/2010Q) but that is rare and you really, really should "do your homework". Then you'll be happy with your decision.
Good luck in your search and I hope you find what you want.
