Whether you're a reseller, collector, or just trying to buy a hard-to-find item, monitoring product availability can mean the difference between success and missing out entirely.
Why Monitor Stock Availability?
Limited Edition Products
High-demand items sell out in minutes:
- Gaming consoles - New releases disappear instantly
- Sneakers - Limited drops sell out in seconds
- Collectibles - Rare items rarely stay in stock
- Electronics - Popular products have supply issues
Business Use Cases
Resellers and businesses benefit from:
- Tracking competitor inventory levels
- Monitoring supplier stock
- Watching for price drops on bulk items
Speed Matters
Popular items can sell out within minutes of restocking. Automated monitoring with instant alerts gives you the best chance of purchasing.
What to Monitor
Product Pages
Track specific product pages for:
- "Add to Cart" button appearance
- "In Stock" status text
- Price changes
- Quantity available
Category Pages
Monitor category or search result pages for:
- New product listings
- "Back in Stock" labels
- Inventory indicators
Setting Up Stock Monitors
Step 1: Find the Right URL
Use the direct product page URL, not:
- Search result pages (too noisy)
- Category pages (unless tracking multiple items)
- Cart or checkout pages
Step 2: Identify Stock Indicators
Look for text or elements that change when stock status changes:
| Indicator | In Stock | Out of Stock |
|---|---|---|
| Button text | "Add to Cart" | "Sold Out" |
| Status text | "In Stock" | "Out of Stock" |
| Quantity | "5 left" | "0 available" |
| Color indicator | Green | Red/Gray |
Step 3: Configure High-Frequency Checks
For hot items, check frequently:
- Critical items: Every 15-30 minutes
- Regular monitoring: Every hour
- General tracking: Every 6 hours
Rate Limits
Some retailers block frequent automated requests. Drifter handles this gracefully, but extremely high-frequency checks may be throttled.
Advanced Strategies
Monitor Multiple Retailers
Don't limit yourself to one store:
- Set up monitors across all retailers selling your target item
- Compare prices when items come back in stock
- Track exclusive vs. general availability
Track Pre-Order Pages
Monitor for pre-order availability:
- New product announcement pages
- "Coming Soon" pages
- Email signup pages (for timing)
Watch for Flash Sales
Retailers often do surprise restocks:
- Newsletter landing pages
- Social media linked pages
- "Deals" or "Sale" sections

Monitor:
- PlayStation Direct

Tips for Success
- Act fast - Have payment info saved and ready

- Check frequently - For high-demand items, every 15 minutes
- Be patient - Restocks happen, persistence pays off
