In very select circumstances, possibly. I got a refund check from DHS/CBP/whoever a while back for some random thing I imported (which turned out to come from Germany, which I only discovered after I bought it…) for which I got tariffed personally. I presume after that particular tariff was retracted and/or struck down.

For the vast majority of consumers buying stuff off the shelf from retailers and vendors who jacked their prices up to compensate for said tariffs, no. Absolutely not. I predict said prices will remain jacked up for the foreseeable future as well, since retailer pricing policies are completely opaque to the consumer, and also notoriously ratchet-like — they tend to only move in one direction.
