目前为止，价格方面的信息仅有一项承诺：通过沃尔玛在线商店服务下单的顾客将享受乘车折扣。
"If this is rolled out properly you would expect there to be a reasonably high threshold in terms of the price and spend commitment to justify the service," commented Julie Palmer, a retail expert at the consultancy Begbies Traynor.
咨询机构贝格比斯·特雷诺的零售专家朱莉·帕尔默评论道：“如果推出得当，为体现这一服务，你可以想象出在价格和支出方面可能会相当高。”
"You'd expect it to be limited to shoppers buying higher value items."
“这项服务也可能仅限于购买高价商品的消费者。”
