Sam's Club piloting online subscription service

NEW YORK — Sam's Club is piloting a new online subscription service — My Subscriptions — that allows consumers to automatically replenish consumables like diapers or printer cartridges, The Wall Street Journal's Market Watch reported Wednesday. 

The service is in direct response to Amazon's Subscribe & Save program, the report speculated, indicating that Amazon is gaining traction in capturing the business of repeat-purchase items. 

"Food is very important to the club business," Mark Miller , an analyst at William Blair & Co, told The Wall Street Journal. "As Amazon expands its food offerings, there's going to be a bigger overlap going forward."
