They take every chance they can get to cheat customers. Duraflex and Everflex are the exact same foam, there is no difference other than what they charge you, and it's been that way for years and years.
The place is such a disorganized mess, if your order is months late it's less likely to be from covid and most probably because your order form has been lost or misplaced.
The markup is crazy ridiculous, it's well over 50%. I estimate it to be around 500%, possibly more. Bottom line is you'll never get what you pay for but if that's your thing... more power to the owner.
Ps. The "wood handle regulators" are just cheap ice picks bought from a brewery
