Up to 10,000 retailers have taken part in a second boycott of Vodafone top-ups after the telecoms giant refused to rethink its planned commission reduction.

As The Grocer went to press, more than 6,300 stores had signed up to take part in the two-day Spar-led protest, which kicked off yesterday. The number was expected to hit 10,000.

More than 5,000 stores refused to sell Vodafone’s top-ups on Friday 11 July after it announced it would slash commission to 5.5% at the end of the month. 

Vodafone refused to back down, but offered not cut rates again for another two years.

“Over 1,000 Spar stores switched off on July 11,” said Spar’s UK trading director for licensed products, Chris Lewis. “The impact on Vodafone sales was extraordinary.” 

A Vodafone spokesman said: “We are doing more than ever before to improve the range of ways people can use Vodafone therefore stimulating more top-ups.”
