Selling this year has been interesting. The volume is much higher than I expected it to be in "recessionary" times, especially with Target and Walmart posting such terrible Q3 numbers. There may be some small impacts to selling this year however I'd venture to guess this is going to be more applicable to people selling less desirable items (off brand cook wear, trinkets, figurines?).
Every other year, I listen to Amazon's guidelines of when to send stuff in, this year being one of them. I sent my stuff to Amazon on the 4th of November and it was inventoried and available in under 4 days. (Not great). I expected it to take a few weeks. It has resulted in some interesting selling opportunities as some competitors stock is lagging to the fulfillment centers. It may be too early to be bringing in sales but alas... better then paying storage fee's.
