My experience was that I ordered supplies from the US warehouse and they shipped from the CN warehouse because, according to them, their US stock hadn’t actually arrived yet. But I only got half my order, so when I contacted my rep, she shipped what was lacking from the US warehouse, which meant I got 2 different batches. I wrote several comments on it under the “anyone buying from ERP” thread. I’m sure it did come from the domestic warehouse because it arrived in a ~week. I think they are trying to fulfill orders as quickly as possible and provide the best customer service they can. But I guess the short answer is you never really know. Their TG has grown a lot in the last couple of months, though, so I think they’re growing quickly and it looks like they’ve added several US warehouses now.
