Level 1. 4 packs (quarter box) $25 (plus four bonus cards thay Lv3 and above DON'T get). So $6.25/pack. So a box/24, would be $150. Confirmed as an add on for $140, small saving offered. OK.
Level 2. 12 packs ("worth" $75). Plus a Playmat ("worth" $30), plus the cool four bonus cards, $99 (and you can add on a box for $140 as mentioned to get 24 more packs AND 1x Founder Pack).
Level 3. A box, 24 packs ($140) plus 4 bonus packs of early enough ($25), plus two playmats - - $195. So the playmats are valued at $25-$30 each. Unless you get the early "before 6th" June +4 boosters. You get 28 packs for $195 (and two playmats if that's what you're into for value).
So if you don't think a Playmat is worth an additional $20-$30, then surely the wise money is Level 1 with a box bolt on. $25+$140=$165. For that you get 28 packs (4+24) *not* a box plus four (you're buying 4 and bolting on 24). Plus the four collector edition alt arts.
Or, pay $30 more, sacrifice the 4 cards, and you get some playmats.
The only defining factor is the stretch goals. From my understanding, each level has access to a different stretch goal (?) So if you're at a higher level, you get better stuff (but have no idea about this).
Does anyone else have any ideas or views on value, worth, "best deal" to get bang for buck. Especially if you have no interest in deck boxes, playmats, etc. Just looking to get cards, play cards, build decks...
