geordie is right.
Both the Chocolate Box table and the Truffle Chair were originally released through the Valentine's Day goals in 2012.
If you're a newer player, the Truffle Chair may be marked
locked by goal. If this is the case, you'll have to wait for it to be relisted in a sale before you're able to purchase it. The good news is that it's likely to happen soon; with V-day not that far off we're sure to have a seasonal sale and they're likely to include this chair since it's a super popular item.
