Buckingham Palace has posted an advertisement for its strawberry preserve, just days after Meghan Markle’s American Riviera Orchard brand unveiled its strawberry jam. The Palace’s preserve is priced at £3.95 per jar, while Meghan’s jam is yet to be priced. Social media users have been quick to point out the decision to promote a strawberry preserve on the palace shop Instagram account, with some suggesting it is a subtle shade at Meghan.
