I don't know if I'm walking into a hornet's nest here, but I found this response to someone asking they would improve FFG's sales if not with their new policy and I found it rather insightful:
How Would You Improve Sales for FLGS?
Short answer: I WOULDN'T.
Long answer: Stop trying to "compete" with online retailers. Just stop. All retailers, just stop. They have every advantage you're never going to have. Online retailers have the selection, price, and convenience of priority-to-my-door-shipping you cannot top. You can talk about "personal attention" and customer service all you want. But the savvy customers, who especially fill a niche market like board gaming, don't need store staff to help curate their purchases. Your customers almost certainly know more about what they like and what they want than your staff can. The customer can specialize in their taste while your staff has to have broad knowledge to help any customer.
As a consumer I don't need nor want a Friendly Local Game Store. I want a Friendly Local Game Space. I want somewhere I can go with space accomodations I can meet my play group, tables big enough to fit games with large foot prints, a comfortable chair, good lighting, like-minded people to talk to when I want to socialize about my favourite hobby.
Be the thing an online store cannot be. Don't desperately try to be the thing you cannot be. Namely, the best quality for value proposition to the consumer. Online retail has an objective and unbeatable edge on that every time. So don't be a store; be a social hub. Be the place where gaming happens in your respective town or city. Be that place where whether I want to play some commander, LotR LCG, Terra Mystica, Scrabble, or Munchkin I know I can get a game in.
Just because you're not focused on retail, doesn't mean you can't engage in commerce. If you've got butts in your chairs for extended stays people need food, they need beverages. There are ancillary products to gaming which make sense to have on-hand as impulse buys or purchases-of-opportunity that people make as needs arise. Busted a sleeve? I'll just grab a new pack. Oh! Shiny dice! CCG singles on the secondary market are a very lucrative business (and have been for many years) for any savvy store. You can even opt-in or out of having cover. I would gladly pay a fiver for some table space. Hell, I already do without it being compulsory! Anytime I know I'm spending time at an FLGS using their table space I buy beverages to give them some money, even if I'm not particularly thirsty it's my way of ensuring something is paid for the use of their space and I'm not just completely freeloading.
Host social events, game tournaments, demo days, have a gaming library for public use (really helps justify that cover charge). Always have something going on. Have an event schedule that has something that would appeal to one type of gamer or another every day. And don't be afraid to adjust dates and times to see when fits that gamer "group" best. And ensure that you give these things proper time and promotion to gain traction.
Don't try to sell me games. I have a world's worth of retail options at the best possible prices at my very fingertips to buy my games; sell me events, sell me interaction, sell me an experience.
