OpenBazaar到底是一个什么样的东西？
粗暴通俗的说下神马是欧盆巴扎！
1:去中心化的全球性自由买卖市场。
全世界最少有20亿人绝对相信阿里集团第三方仲裁担保，Openbazaar是加密学做仲裁担保，无需信任的信任来自于数学，而不是人。
2:Openbazaar是个不起眼却伟大眼光的开源项目。
3:目前已经有人开始在上面贩卖其他，和***。
4:没有中心服务器，靠的是分布式节点自动维护。
5:只能用bitcoin交易。
待更新。
亚马逊 add-on item制度合理吗？
其实Add-onItem并不属于新政策新措施的范畴，这个项目在亚马逊系统存在由来已久，只不过是之前亚马逊并没有特别强调此措施，当前把这个项目应用于很多FBA发货的低价格产品，所以才显得格外显眼。
具体来说，显示“Add-onItem”标志的商品，都是经由FBA发货的单价很低的产品，亚马逊系统核算，这类产品为亚马逊产生的利润微乎其微，而配送成本已经高于利润，为了提高利润空间，亚马逊对这类产品设置了一个限制，当你单独购买该产品时，订单总金额必须超过25美金方可下单，即便你是Prime的会员，也同样要满足订单金额满25美金才可以。
亚马逊对此给出官方解释：Add-onItemsshipwithordersthatinclude$25ormoreofitemsshippedbyAmazon,excludinggiftcards.
对于顾客来说，购买这类产品需要满足总订单金额25美金这个底限，这样就会让部分只是想单独购买某个产品的买家不能达到标准而放弃购买，这样一来，对于卖家来说，无疑会错失一部分顾客。
所以，Add-onItem对于卖家来说，绝对不是一个好项目。
那么卖家该怎样绕过Add-onItem的发生呢？
当一款产品，因为卖家价格设置过低，系统自动会把产品加入到Add-onItem项目中，如果你的账号一旦出现此标志，此时不妨把价格调高，随着价格的提高，Add-onItem的标志也会随之消失了，在此时，可以通过朋友的账号刷几单，当成交发生后，再试着把价格调整到你自己预期的低价位，此时，Add-onItem一般也不再会跟随而来了。
遇到Add-onItem的卖家，不妨尝试一下看看。
produce可数么？
produce作名词是不可数名词,指一切农产品,天然产品.其前不用冠词,也不用复数.Wecanbuyfarmproduceonthemarket.我们可以在市场上买到农产品.Thefieldproduceisshippedbytraintootherpartsofthecountry.用火车把农产品运送到全国的其他地方.product是个可数名词
