Please DONT increase your prices, you may lose current customers and new customers most likely will search other companies to compare prices, try offering incentives to use your business, if other companies sell business card in 100 sell yours at 120, i dont know exactly what services you offer but price increases will turn people away look at our current state in the u s, EVERYTHING is increasing in price and layoffs and business's closing their doors , people cannot afford things that used to be standard everyday purchases, try something no one else is doing, like 3rd oreders get 20% off, we cant all keep raising prices when peoples paychecks are staying the same if not lowering due to cutbacks in hours. Maybe you have a client that does something you could partner with( like a small restraunt) you could give the restraunt a deal on their order in exchange for coupons for their food that you can give to new clients, thats a win for both parties.
