save money is waging war against my desire to support the local economy.
First you must save your economy before you save the LHS economy. The USA economy is based on competition. This competition is what keeps the prices from sky rocketing up.
Our LHS have competitive prices compared to some online stores. For the most part I purchase the nitro and other miscellaneous items at the LHS. Airplanes and engines I purchase online. My decision is based on total price. Remember that purchasing online and at your LHS both have their advantages and disadvantages. Weigh them out. IMOP just support both. Can't put all your eggs in one basket.
As far as advice, that is for free. Whether at the LHS or the field. Take any advice with a grain of salt. Get more than one opinion as for all advice is just that... an opinion.
Good luck in your dilemma
