I bought mine via the Hasbro link.
In about a week from when I mailed the check, I had a letter acknowledging my order and letting me know that some items were out of stock, but what could ship would ship shortly.
About 3 days later I had MOST of my order… 2 additional sets of AA/IC’s, Chips/Dice, and all non INF units. My INF was backordered.
About a week later, I received 1 set of INF.
The next day I received a refund check for the other INF set.
Based on my experience, I would recomned only buying a single additional set of pieces… tripling the initial pieces was overkill, and I never run out of INF thanks to the extra chips.
HOWEVER…
Tripling your chip count is probably a GOOD idea. Even with a triplicate set, AND my red chips from my Classic set, I do still run out of red chips from time to time…
