Signet Jewelers Ltd. reported a 54.4% increase in online sales for its third quarter ending Nov. 3. Signet, which owns brands including Zales, Kay and Piercing Pagoda, said 10.5% of total third-quarter sales, or approximately $125.1 million, came from e-commerce, compared with 7% or $81.0 million during the same period last year.

However, sales at its largest digital property, JamesAllen.com, had slower growth than previous years, CEO Gina Drosos said on an earnings call transcribed by Seeking Alpha. The online-only brand grew sales 13.6% year over year to $52.5 million for Q3.

“In the third quarter, we started collecting sales tax in an additional 24 states such that by the end of the third quarter, sales tax was being collected in states representing about 50% of our revenues,” Drosos said. “[James Allen’s growth is] a sequential slowdown which we expect to continue over the next few quarters as we work through the implementation of sales tax in additional states.”

Signet is one of many retailers adding sales tax to the online checkout process in the wake of the the Supreme Court ruling in South Dakota v. Wayfair, which allows states to collect sales tax from online retailers that don’t have a physical presence in the state. Because sales tax is often based on an order’s value, higher priced items like jewelry have higher sales tax totals.

“We are testing a variety of customer initiatives, and remain positive about the long-term growth prospects for James Allen, as well as continuing to leverage their digital capabilities across our banner websites,” a Signet spokesman said in a statement to Internet Retailer.

Drosos also said Signet, No. 102 in the Internet Retailer 2018 Top 1000, is tracking how its competitors who already collected sales tax are doing in the same markets to measure any significant problems, but she feels that the brand won’t be affected by the slowdown in the long term.
