Deliteful Boutique

Their prices are cheaper than other Squishy online stores, but they come defected. All sales are final, so returns aren't allowed. You cannot leave bad reviews on their site as all reviews must be approved by them in order to show up. From their website FAQ section:
Returns
"All orders are finalized, therefore we do not accept any returns. In any rare cases where a buyer would like to return any goods. You will be responsible for postage costs of returning the item. We recommend using registered mail to return items incase of lost or stolen goods."
Defected Squishies
"Defected squishies are very common, we are not responsible for any defects as the squishies are received the way they are from suppliers. Issues such as tiny air bubbles, or small defects are not compliant with our terms for any refunds. We would state on the products page if there are any visible defects such as big tears, rips or any other obvious faults. Please refer to our terms and conditions on our refund policy."
