Store Armory is a small WordPress/WooCommerce plugin shop whose flagship product is Waitlist Pro, a back-in-stock and price-drop waitlist plugin for WooCommerce stores. When a product goes out of stock, the plugin automatically injects a sign-up form on the product page so shoppers can join a waitlist without creating an account — just an email address is required. Once the item is restocked (or its price drops), Waitlist Pro sends automatic notifications through email, SMS, WhatsApp, or web push, and it supports per-variation waitlists so shoppers can wait for a specific size or color rather than the whole product. The plugin is built for GDPR consent, background batch sending for large notification runs, and is compatible with WooCommerce's High-Performance Order Storage (HPOS) and the newer Cart & Checkout Blocks. It reports on recovered revenue and conversions from waitlist notifications directly in a WordPress admin dashboard. Checkout, licensing, and delivery are handled through Stripe: buyers pay, then immediately receive a downloadable plugin ZIP and an emailed license key, with automatic updates included for the license term. Store Armory also lists a separate WordPress security/incident-response offering (Forvault Security Pro) on the same site, aimed at hardening sites and responding to hacked/compromised WordPress installs.

Pros & Cons
Pros
Multi-channel restock/price-drop alerts (email, SMS, WhatsApp, web push) beyond the email-only waitlists most competitors offer
Guest sign-ups mean shoppers can join a waitlist with just an email, lowering friction and capture rate
Compatible with WooCommerce HPOS and Cart & Checkout Blocks, so it works with modern WooCommerce setups
Simple, transparent pricing with a 14-day money-back guarantee and instant Stripe-based delivery of the plugin ZIP and license key
Lifetime license option ($199 for unlimited sites) avoids recurring subscription costs for agencies managing many stores
Cons
Single-purpose plugin (waitlists only) rather than a broader marketing/retention suite, so stores may still need separate tools for email marketing or SMS campaigns
WooCommerce/WordPress-only — not usable on other ecommerce platforms like Shopify
Very small, newer vendor with no visible public customer count, reviews, or long track record beyond its own site
Support is limited to email (no live chat or phone support advertised)
