One-Day Churu Auction Copy

I need sharp, platform-ready copy for a 24-hour reserve-price auction that I’ll be running simultaneously on eBay, OfferUp and a dedicated Shopify flash-sale page. The product is multiple cases of Churu pet treats and buyers must clearly see the value and the urgency:

• Each case = 8 boxes
• Each box = 6 packets
• Each packet = 4 Churu tubes
• That’s 192 tubes per case
• Offer ends at midnight, Oct 6 , 2926

Deliverables I’m expecting from you
1. A punchy, character-compliant title for each platform.
2. A persuasive description that lays out the quantities above, highlights the single-day timeframe, states the reserve-price format and urges fast action.
3. A short bullet section I can reuse to list shipping, payment and return terms.
4. Suggested hashtags / keywords for added reach on each site.

Acceptance
Copy must be error-free, paste-ready, and stay within the individual platform limits while maintaining a consistent voice across the three sites.
