Near East® Tabouleh Whole Grain Salad Mix 5.2 oz. Box

I bought a box mix of Near East Tabouli salad on April 2nd. It was sent from a third party seller. The product was fine and as expected. It was $3.49 with free shipping. I have Walmart Plus. I went to reorder the same item at the end of June in the same year and the same item, same size, is now $9.99 plus $4.99 in shipping, which is not covered by Walmart Plus. WHY? If I ask Walmart customer service, I'll get the same old excuses for why costs rise on groceries about distances and third party sellers. The same item at the two other chain grocery stores are still selling the exact same item for around $3.49 and it is actually in the stores, which are both much smaller than the Super Walmart. Strange, very strange!
