The SMS Flash Sale Blast Writer

Act as an SMS marketing expert. Help me write an effective SMS message for a flash sale that fits within the 160-character limit and drives immediate action.

• Sale Details: [e.g., "Flash Sale! 40% off for 2 hours only."]
• Link to Sale: [e.g., "https://example.com/flash"]

Task: Write 3 versions of an SMS blast. Each must be under 160 characters, include the core offer and time limit, convey extreme urgency, and contain the shortened link. Use abbreviations and emojis wisely to save space. (e.g., "FLASH! 40% OFF EVERYTHING. 2 hrs only. Shop now: [link] ").
