About Tweakday: Auto Add‑ons & Fees
Tweakday auto-attaches fees, warranties, insurance, and free gifts to specific products at checkout — based on rules you set. Sell a phone, a warranty attaches. Sell a fragile item, a handling fee adds. Per item, not per order. Quantity scales automatically. Multiple add-ons per product. Update bundle title and image at checkout. No widgets. No theme edits. No Shopify Plus needed. Free or paid add-ons. Auto-creates virtual products for insurance or warranties — no manual setup.
