Stop overcharging us- we purchase online because its cheaper- A LOT CHEAPER! Quit sneering when we bring a tank that has been inspected somewhere else and smile and thank us for the business and we`ll probably come back again. If a dive shop refused to service my equipment because I purchased it online- I would laugh (knowing that this dive shop would soon be out of business because they were jerks and lacked the people skills to establish and maintain a loyal customer base), then I`d walk out and tell every divebuddy I crossed that they were jerks and didnt want my business. Then I`d send my stuff to another shop or an online shop for service. Either way you lost another sale and many customers. We as divers will support a local shop that is knowlegable, frendly, service orientated and dosent over charge us. Keep overhead down to keep prices down, the best dive shop I`ve seen was run out of a mans garage it was open for 15 years before he retired (not went bankrupt)- I miss that shop.
