Peddler variant, or cantrip money, is a catch-all term for cantrips that give + . They fit very easily into almost any engine, since, as long as they are not drawn dead by a terminal draw card with no actions remaining, they can always be played to increase buying power without obstructing your access to other engine cards.
The simplest possible Peddler variant—a card that simply gives +1 Card, +1 Action, +Donald X. Vaccarino has commented that leaving this niche unfilled gives him more flexibility in designing variants. Consensus among analysts was that such a card, if it existed, would be balanced at a cost of roughly ; however, Poacher was eventually introduced with a cost of , and is almost strictly worse than "vanilla peddler".—does not exist; all Peddler variants carry at least one other bonus, penalty, or quirk aside from the cantrip-money effect.
 List of Peddler variants
The Peddler variants, and their differences from the notional "vanilla Peddler", are as follows. Cards in italics have been removed.
 Unconditional Peddlers
These cards always give at least +1 Card, +1 Action, and +(or the equivalent).
- Dominion: Poacher — discards a card from hand per empty Supply pile
- Dominion: Market — gives +Buy
- Seaside: Bazaar — gives +2 Actions instead of +1
- Seaside: Treasury — may be top-decked during Clean-up if you do not buy any Victory cards
- Prosperity: Grand Market — gives +Buy and + instead of , but cannot be bought with Copper
- Prosperity: Peddler — has a variable cost that enables tricks with +Buy and trash-for-benefit
- Hinterlands: Highway — reduces costs by instead of giving +
- Guilds: Baker — gives +1 Coffers instead of +
- Adventures: Caravan Guard — the + is delayed until next turn
- Adventures: Artificer — also a discard for benefit gainer
- Empires: Emporium — also has a potential on-gain + bonus
- Menagerie: Fisherman — can cost less if you have an empty discard pile
- Allies: Skirmisher — performs a discard attack if you gain an Attack card after playing it
Some cards have all three bonuses that make up a peddler but cannot be used in the same way because they do not maintain handsize:
 Conditional Peddlers
These cards have cantrip-money effects that are not always activated.
- Dominion: Merchant—is a Peddler variant on a turn on which you play Silver
- Intrigue: Conspirator—is a terminal silver if it is the first or second action played on a turn, but a cantrip later
- Cornucopia: Tournament—may have its +Card and + blocked if an opponent has a Province in hand; can gain Prizes
- Dark Ages: Ironmonger—is a cantrip that gives + if the second card of your deck (from the top) is a Treasure card
- Dark Ages: Mystic—gives non-terminal + but only draws if you can guess the card it's going to draw
- Empires: Settlers—instead of giving + , can put a Copper in your hand if you have one in your discard pile.
- Empires: Chariot Race—only gives + if you reveal a more expensive card from your deck than the player to your left.
- Allies: Courier—allows you to choose a card from your discard pile to draw and plays it immediately instead of giving +1 Action—so it's not consistently non-terminal.
- Plunder: Cabin Boy—optionally gives + on the next turn.
- Plunder: Harbor Village—only gives + if the next Action you play after it also provides + .
 Marginal Peddlers
These cards are not normally thought of as Peddler variants.
- Dominion: Vassal—a terminal silver that can play the top card of your deck if it is an Action, which is kind of like giving +1 Card and +1 Action when it happens.
- Intrigue: Tribute—can give +2 Cards, +2 Actions, and + under rare circumstances depending on the top of the deck of the opponent to your left.
- Intrigue: Mill—gives + only if you discard two cards, so it doesn't maintain handsize.
- Intrigue: Mining Village—is a village with an optional one-shot +
- Prosperity: City—acts as combination Village, Laboratory, Market if two supply piles are empty
- Nocturne: Secret Cave—requires you to discard 3 cards first, so it does not maintain handsize, and its + is delayed until next turn.
 Donald X.'s remarks on the lack of Vanilla Peddler
Peddler (are we clear on what I mean here, yes, okay) would probably be fine. I mean it would be good, but it would be acceptable power-level-wise.
