I also ordered the fingerling from amazon, as did my friend. Hers is ‘stuck in customs’ and they have issued a refund, mine is still coming apparently.
I’ve asked for a refund and it has been processed. Interestingly I emailed the seller, but it wasn’t the seller who replied but amazon itself giving me the refund (previously it’s been the seller who replied).
My friend also noticed if you search amazon for fingerlings they have all gone! There are no hits. So I think the whole damn thing was a con all along from various sellers.
In fact as a word of caution in general- this is the second item I ordered from China through amazon and neither arrived. I was refunded though.
I have ordered from China through eBay, wish and Ali express and I always get my goods.
I’m not sure why amazon doesn’t make it but my experience is that it doesn’t. So I would advise not to buy these kind of deals through amazon and if you are looking for a Chinese cheap deal to stick with one of the others I’ve dealt with.
