- r***a (55)- Feedback left by buyer.Past 6 monthsVerified purchaseI know the seller has no control over the weather or the USPS, but if my package still hasn't arrived by January 24, 2025, I will ask for a refund of my as the USPS has FAILED to deliver my package. It was scheduled for delivery on Jan 8th but the snow and ice storm caused a delay, which even though that is understandable, the roads in Louisville, where the package is supposedly being held up, are clear as are mine in New Albany. 10 days later and my package still has the same status as on 1/8!!
