A store with staff members who want to sell books,have personalities and want to help.
i am a salesperson and i always have people referring their friends to me. a referral program for friends and shit would be nice. if you get someone to start a pull list with 5 or more comics then you can get one free comic per 5 comics while your friend gets a 6th comic for free as well.
a points system that tracks how many comics you have bought with your email/phone number/address, you get free discounts and posters and merchandise when buying comics and shit.
marketing (got a BS in marketing as well)
i dont see any advertising for books or comics, yet i see tons of advertising for video games and the target audiences are very similar.
I am in sales as well... marketing is a tricky thing. How many times do you see CAT commercials? CAT is a 50 billion $ + per year company in revenue. I think the movies etc from Marvel and DC are advertising for the industry... though seeing image commercials during walking dead episodes would be brilliant and worthwhile.
CAT has reps that go to business and sell/rent their equipment to other companies. in their case, the average retail consumer probably never has heard of CAT besides the boots that they sell at WalMart, its a completely different market.
with comics, you are selling to the same people who purchase movies, video games, etc...
in other words, its retail...
im not saying they gotta go crazy with advertisement because at the end of the day word of mouth is stronger than any ad, theres only one comic shop that people know about here in miami, i had to look up the other shop
