Our love for Power Miners here at FBTB runs deep. I’m sure I could make a metaphor about that last statement and underground mining if I tried hard enough.
If you missed out on the Target-exclusive 8708 Cave Crusher during it’s short production run, Target.com has restocked on the item. Hit the link and do a search for “LEGO Cave Crusher” to see the product page. Alternatively, you can dial your browser to Amazon’s product page and still order from Target. Just be sure Target.com/ITC is selected as the seller. You end up paying tax and shipping, but it’s got to be better than trying to acquire one on the after-market.
