UK-founded cashback marketplace OnBuy has accelerated its European expansion, launching eight new markets across Sweden, Norway, Denmark, Poland, Hungary, Romania, Czech Republic and Switzerland. 

The move brings OnBuy’s total European presence to 21 countries. It says this gives UK retailers fast access to millions of additional customers.

The expansion follows OnBuy’s expansion into 12 initial European markets, which it says have delivered 152% quarterly sales growth and a 300% increase in average monthly site visits in the second half of the year.
