Hey Dennis, I tried googling the store you mentioned and pulled up a couple, but neither appeared to carry diy kits or flavors so I can't really answer that question... However, you have landed in a forum which is in, for me anyway, the best source of DIY info and flavors you could find. I went
through several before I found Kimer and Renaissance at the
OneStopDIY forum and the
OneStopDIY site. After 5 years OSDIY is still my go to supplier.
First, mix small batchs to refine your flavor and you may find that the mix improves if you steep (age) for a day or more. Make sure you write down everything and label every mix so you don't confuse them if you're steeping several at a time (been there-done that more than once.) The big thing is to read/experiment/enjoy... the juice you enjoy may be very different from what another vapor enjoys so mix to your own tastes.
