aerbubblr review for Insureful Shipping Protection

When the shipping protection widget is enabled, the app creates a product with 100 SKUs for percentage-based pricing (ranging from $1 to $99.98). The widget calculates a protection fee based on the cart total and your set percentage, then selects the nearest higher-priced variant. For example, if 2% of a $220 cart is $4.40, the widget will display the closest higher variant, $5.04. WHAT??
