when she told them that she was taking a college scuba course, and felt a bit overwhelmed.
A sad reality is that walking into a shop ignorant of your needs and the market, open and perhaps even a bit eager to make a large purchase based on staff recommendations, is fertile soil to be taken advantage of. One might suggest:
1.) Do a little reading online at a reputable online vendor and see what their packages cost.
2.) Make your first trip to the dive shop a visit to see what product lines and models they carry, not a trip to buy a full set of gear.
3.) Listen to them, take notes (including brand and model BCD, regulator, dive computer, etc...they sell), go home and read some online reviews.
4.) Dive shops serve a worthy role, and if there's local diving may be your source for air fills. If the price buying from the shop is at all close to the online price, and you basically used the dive shop like product showroom (e.g.: tried that wetsuit on for fit, tried the BCD on) and drew on the expertise of their staff, please factor in the added value they bring and consider financially supporting them.
5.) Be mindful you may want to get a regulator brand they do routine servicing on.
6.) Research dive computers separately; don't pigeon-hole yourself into just what the dive shop sells.
