Good Usenet blocks should not expire: prepaid gigabytes stay on your account until you use them, with no calendar deadline that zeroes balance at month end. Many cheap promos violate that expectation with time-limited quotas or confusing recharge rules. When you shop the block accounts hub, filter for non-expiring language, then confirm in the merchant terms before you pay. Fill blocks from NewsDemon, Usenet.Farm, and ViperNews are typically bought for that idle-until-needed behaviour in SABnzbd.
Never-expire definition
Never-expire means your remaining GB count drops only when NNTP downloads consume articles, not when a billing cycle flips. This matches how optional Priority 1 servers should work: months can pass with zero fill usage after you stabilize a solid unlimited primary on Priority 0. If a deal page says "valid for 12 months," that is a calendar block, not the fill insurance model most r/usenet stacks recommend.
Fake blocks to avoid
Watch for time-boxed allotments marketed as blocks, plans that force monthly recharge to keep unused GB, or "unlimited" trials that throttle after a cap. Another trap is buying a second Highwinds brand as fill when you already own Newshosting; that is the same backbone, not diversity. Read block vs unlimited and the backbone map before checkout.
Top-ups and recharges
Legitimate providers let you add GB bundles that stack onto the same username without resetting your balance to zero. Save invoices and screenshot remaining GB after each top-up. Optional servers in the SABnzbd setup guide help ensure top-ups are not burned by health checks or failed queue items pulling from Priority 1 accidentally.
Merchant checklist
Before pay: confirm non-expiring GB in writing, confirm backbone differs from your primary, confirm SSL port 563, confirm optional fill role in your client plan, and size GB using our block size guide after you log misses. EU primaries on Eweka pair well with Express or NL fills; US primaries on Newshosting pair with NewsDemon or Farm, not UsenetServer twins.
Support tickets about missing GB after a promo often trace back to calendar-limited products purchased by mistake; keep the checkout SKU name in your notes.
