I used to find auctions around Christmas/Holidays sometimes go for a little lower than other periods in the year. It’s not universally the case, but as people tend to be busier auctions can sometimes go unnoticed and you can get some good prices on things. If you’re sensitive about what you pay I’d recommend waiting until then, and if you can’t find anything for a “good” price around then to just by as you can in the new year. Most set cards, even if they’re the chase, will be available again down the line. I think that should alleviate some stress over it. It’s more stressful dealing with promos/trophies where there’s a bit more uncertainty
