I ordered two sets of "twinkle" lights. Only every 6th bulb flashed. Not a true effect. No where in the description was this mentioned. I returned them and between restock fees and their prepaid postage the cost was half the cost of the sets.
I asked at FedEx how much the shipping should be and it was half what they took for the postage. I figure they make profit from restocking and overcharging shipping.
