Out of Stock and Backorder?????

Why is it that 98% of the River Hobby and Quanum Vandal parts are either out of stock or on "backorder"? This is so ridiculous. Why even have them listed if you're never going to have them available? I have been trying for MONTHS to get parts for my VRX RH1017 and this site NEVER has them available despite having them ALL listed. What a joke!! Let's take the item located below as an example: https://hobbyking.com/en_us/aluminum-chassis-plate-1-10-quanum-vandal-4wd-racing-buggy.html?wrh_pdp=2

Available at the END OF MAY 2019... MAYBE????!!!! C'mon man!!! Surely you guys can do better than that. Totally and completely disappointed. Looks like I'll have to get my parts from JHC Hobby and pay the ridiculous shipping they want to charge... ($17+ for USPS Priority shipping even if the part only costs a $1.50), but at least they have the parts in stock. Tighten up Hobby King. Tighten up!
