I decided to just restrict myself this year to retail purchase. I bought a blaster from Target (to get the Target Red cards), a Mega Box at Target (because there were two packs of Topps Update Chrome in the box) and 2 rack packs at WalMart (to get the WalMart Blue cards). I got a good selection of cards and inserts, in fact all the inserts except the low serial numbered ones and relics. Apparently, Topps Update Chrome is only available in the Mega Boxes so I'm glad I bought some.
I was surprised by the price differential among the 3 packages. The blaster cost $0.27/card, the rack packs were $0.15/card and the Mega Box was $0.37/card.
You know and love (at least I do) the design so I'll only show a couple and then get into the inserts.
In Series 1 and 2 Topps had 1972 Mini cards. In Update they have 1971 Mini cards. Who knows why.
The blaster box had this nice manufactured patch card as an extra.
Here's a Home Run Derby subset card from the Chrome Update
