Bestseller Is the Ruby Shop Where Pack Size Decides Everything

Bestseller is the ruby shop with special offers — it sells units, tools, and above all event tools for whatever event is currently running. At first glance it's just a plain price list, but hidden inside it is one rule that runs through the entire assortment and decides whether you pay full price for the same goods, or just a quarter of it. This article breaks down the price list, works out the per-piece prices, and shows exactly where the line falls between a good purchase and rubies thrown away.

The Pack Rule Behind 100, 1,000, and 5,000 Pieces

Event tools in Bestseller are sold in three pack sizes, and the ratio between their prices is completely constant across the entire shop:

In other words, for twelve and a half times the price of the small pack, you get fifty times the goods. The 5,000-piece pack is four times cheaper per piece than the 100-piece pack. You can verify this on any item in the shop:

The practical takeaway is crucial: buying small packs almost never makes sense. If you know you'll use up a given tool over the course of the year, the large pack is cheaper even accounting for part of the stock sitting unused.

Relic Units and Veteran Units

Bestseller sells two lines of level 10 units, again in two pack sizes:

Veteran units are therefore cheaper per piece than relic units (0.66 versus 0.875 rubies for the large pack). The price difference matches the difference in power, though — level 10 relic units are among the strongest in the game. For topping up your army before a big event, veteran units offer the better price-to-power ratio; relic units make sense where power per unit is what matters, such as when wave slots are capped.

For reference: 10,000 veteran units cost 6,600 rubies. That's roughly a fifth of the price of a single sacrifice for Beatrice (69,999 rubies) — in other words, a full army for one big event costs less than a single attempt at a legendary general.

Basic Tools and Resources

Defensive and offensive tools are sold in packs of 200, food in packs of 1,000:

Offensive tools (Breaching Tower, Shield Wall, Heavy Ram) are noticeably cheaper than defensive wall equipment — a Breaching Tower costs 1.35 rubies versus 3.40 for a Fire Moat. Buying defensive tools with rubies only pays off in rare cases; making them in the defense workshop costs just resources and time, while rubies are better spent on things you can't produce yourself.

Event Tools and Their Point Bonuses

The largest part of the shop is made up of tools for whatever event is currently running. All of them combine a percentage bonus to event points with, in some cases, a weakening of the target's defense. Here's an overview of the strongest tool from each family (prices for the 100-piece pack):

Alongside these are siege tools, which combine the bonus with weakening the defense. Here's a sample from the Glory family (always 100 pieces):

The Nomad and Samurai counterparts are meanwhile far cheaper than the Glory ones: the Tree Trunk Ladder and Folding Ladder cost just 100 rubies for a hundred pieces and give -25% wall protection. Anyone farming Nomad or Samurai camps buys siege tools five times cheaper than a player in a Glory event.

The Time-Skip Exchange

Bestseller also works as a time-skip exchange — instead of paying with rubies, you pay with skips of a different length. The exchange rates are set up so that small skips can be combined into large ones and vice versa:

The key thing to know is that the exchange takes a cut in both directions — no rate is a fair one-to-one trade. The loss runs roughly from 4 to 14%, depending on what you're exchanging for what:

The best deal is therefore combining skips upward into a 24-hour skip, where the cut drops to 4%; the worst are small exchanges like seven ten-minute skips for one one-hour skip (14.3%). The practical takeaway: only exchange when you genuinely need a different skip length — every trade made just "to tidy up your inventory" costs you real time.
