Supply chains have been disrupted across nearly all industries. I had an HVAC repair that was problematic due to a shortage of pvc. Look in drug store aisles and you can readily see that certain medicinal ointments, creams etc are not available and are on back order. So many suppliers ramped up on "covid" supplies...you can find hand sanitizer and masks by the case but good luck finding more mundane items. Heck, last year landscapers were struggling to get trees to plant!!
Hopefully things will ease up this year.
