How Omnitub Replaced Checkout Blocks with Flare to Generate £48k More Sales Each Month.

The Challenge

Omnitub sells large, made-to-order baths — and needed accurate delivery date visibility by country and shipping method at checkout.

Their previous setup using Checkout Blocks caused frequent issues:

• Checkout logic broke or didn’t load correctly

• Delivery options were unclear or incorrect

• Customers were either confused or dropped off

With an AOV of £980, every failed conversion was costly.

Why Omnitub Chose Flare

Flare offered:

• Reliable checkout block integration for Shopify Plus

• Conditional logic by shipping method and destination country

• Full control over available dates and rates — no custom dev work

Flare made it easy for customers to choose accurate delivery dates — no more abandoned checkouts or frustrated support tickets.

Getting Set Up

Omnitub replaced their Checkout Blocks implementation with Flare’s delivery date picker and:

• Applied rules by shipping method (standard, express)

• Configured logic by country (UK vs international delivery windows)

• Set fallbacks to guarantee a valid ship date was always applied

Results

✅ 63% lift in conversions within 2 weeks

✅ £24,400+ additional revenue, based on AOV and CVR uplift

✅ Accurate delivery visibility for every customer

✅ No more broken checkout logic

Quote

“Flare increased our conversions by 63% in 2 weeks — by letting our customers choose their delivery date.”
