Regarding the specific dynamic of the miners market, there is a possibility that the miner’s price has changed when we receive your payment and we might need to refund your order.
We use a batch process for all the miners orders , and that we have each batch at quite limited quantities .The price of different batches of miners is different even though it’s the same model of miner . They are selling pretty fast. Regarding the highly variable and demanded market , the price could be different every day for in stock miners . So there is a possibility that the miner’s price has gone up when we receive your payment and we need to refund you for the order.
