I that case, you'll have to rely on Avalon's testing.
To quote Steamboat:
"Though Avalon has stated each chip will be tested prior to shipping, there are concerns regarding chip failure rates from batch purchases. The following solution will be adopted in the event faulty chips are discovered.
For future orders:
All customer orders after the timestamp of this post will be responsible for purchasing any additional chips required to ensure the completion of the requested number of assembled units. The amount of additional chips required is based solely on the discretion of the purchaser, and their personal anticipated failure rate of the Avalon chips. Some members of the community have suggested between one and five percent as an acceptable range to mitigate the risk of receiving a faulty chip."

So, at least to my mind, if you're just taking delivery of the chips, then you are not completing assembled units, through Steamboat at the time, so you're just taking your chances buying the chips.
I'm sure somebody can correct me if I'm wrong.
Of course, if you don't want your chips, I will gladly take them off your hands for what you paid for them. I won't even ask you to test them.
