These are very, very YMMV as I found this deal at an Ollie's Bargain Outlet. I found a full booster case of Star Trek CCG Mirror, Mirror expansion cards at my local store in Casselberry FL. Each box of 30 packs was $7.99. These are 20 years old and were a shock to find. I know they aren't the best set ever, but they were a huge trip down memory lane. Link below is picture of box with pricing.
Please let me know if I can provide any additional information as this is my first deal post.
