Wiring I use has gone up over 50%.
Parts I use to create the fire effect for ACNC and TMNT went up 2.5X+ in the USA (from $4 each to $10-12 each [was $12 earlier into Covid], and the process to modify them for modding can damage them). I tried to get another 200 out of China, and it took over 3 months to find I'd get about 5 of the branded part I ordered, then a bunch of unusable knockoffs (white box) with the wrong effect (slower/dimmer) and near impossible to dismantle without damage for modding.
Just put in a new order for the PET plastic I use for several mods, and surprisingly the price is actually a fair bit cheaper (compared to Jan. 2020 from my last bulk order).
