A device and method for merging pre-sequenced products includes at least a first and a second feeder mechanism. The first feeder mechanism feeds a stream of first pre-sequenced product and the second feeder mechanism feeds a stream of second pre-sequenced product. A reading device reads product information of each product of the stream of the first and second pre-sequenced product. A pausing device pauses one of the first stream of pre-sequenced product and the second stream of pre-sequenced product based on the information read from the reading device. The product from one or both of the stream of first and second pre-sequenced product having the same product information is organized into a sequentially merged order.
