Double posting for some reason but worth noting:
No VAT or Tax and no import duties means:
1- Illegal business
2- Not shipped via Aramex oversea ( no way as I have a business account at Aramex, I can dig deeper but not worth the hassle)
3 - They list expired stuff on Ebay
4- Ebay listing is legit but the whole business raises red flags everywhere.
5- Pay upon delivery is available at Aramex. They hold the cash until you receive your items
6- No business in Lebanon is accepting 1515LBP/USD ( except for fuel, bread and medical stuff... Ahh yeah and Uber )
If you look below you will notice that at almost 3300 USD/LBP nowadays, you're technically paying $1550 for an iMac that was sold on Ebay for 2500 USD ( it's the same item, fetched from Ebay as I had to search in google cache)
Note that NO iMac comes preinstalled with 24GB of RAM. It's either 8,16 or 32GB factory installed.
So let's all sell our stuff on Ebay, get paid in GBP by them then resell it on Ebay to them... yay infinite cash.
