 When you buy reserved volume (or quota), you prepay for data at significant discounts. Your prepaid, reserved volume can be allocated on either a pooled basis between projects, or, if you have [Spend Allocation](/pricing/quotas/spend-allocation/) enabled, it can be set on both a pooled and a per-project basis. Unused reserved volume expires at the end of each billing month.
 
-Each Sentry plan includes different amounts of reserved volume. For example, our Team plan includes a minimum of 50k errors, 100k performance units, 500 replays, 1 cron monitor, and 1GB of attachments per month. To see prepaid pricing for each plan, check out our [per-category-pricing](#per-category-pricing).

 ### On-Demand Volume
 
-Buying on-demand volume lets you control the maximum amount you’ll pay for overage each month after your reserved volume runs out. If you go over your on-demand volume, you’ll still have access to previous event data, but any new data you send will be rejected and you won’t be charged for it.
