Dealing with sales calls as I do, calls about things you're not interested in are annoying, and calls about things you are interested in are welcome. I'm always interested in talking about music and guitars and equipment, personally. Sweetwater is providing service, I'd try taking their calls with grace and recognize they aren't a vending machine. You might need the rep on your side later for an issue, or a discount, or to find out about something that isn't advertised once the rep knows what kinds of things you're interested in. Plus they're professionals in the music business - it's good to have contacts. They don't have to be strangers.
