Commission sales can be lucrative in some career fields, GC is not one of them. The biggest reason there is such high turnover of employees is that it is so hard to make a decent living working at GC. The amount of time and energy you have to put into closing a significant sale is not rewarded by a significant commission. You will also be selling mostly lower end instruments, GC doesn't stock many high end instruments because of cost, very few people are buying 4K+ drumsets or guitars, so the instruments will be entry and mid level instruments, meaning much lower commissions for salespeople. The amount of sales you have to make to even MAKE commission is huge, most salespeople do not even make enough in sales to cover their hours (you have to make enough in gross/net to cover your hours for the pay period, if not, you do not receive commission, just your hourly pay) and make commission, so they are essentially working for minimum wage. GC also does not allow salespeople or dept mgrs (I was a drum dept mgr) to give regular customers better discounts, they allow salespeople to give a 10% discount on a single item, meaning if you buy 5 pairs of drumsticks or guitar strings, you only receive 10% off one of those pairs of drumsticks. Store managers even wanted me to employ ridiculous sales tactics, like looking at a mom's handbag or shoes to tell what kind of money they can spend on a drumset for their son. As stated earlier, you will be selling entry level and mid level items, you cannot special order higher end items to have them in stock when that person comes in that wants something better than entry level and has to money to but it. There is nothing to upsell TO when all you carry is entry level drums and hardware. The only great thing GC did for me was motivate me to get a better education and better skills so I could leave companies like GC.
