BigBuy ‑ Dropshipping carriers

The worse dropshipping services . They are misleading when they describe their service and they do not refund your hard worked money.
Stay away, they are thieves .
They have described the shipping fees for my clients between £0.91 - £5.44 /KG and they said that their shipping app works with Basic Shopify Annual subscription.
Well, I have tried the service by purchasing something small ( less than 1 kg) and they have asked double for the shipping price . Their app only works with Advanced Shopify Annual. So nothing like they have described. If other people went thru this with this company , lets do something about them. They do not refund my money even thou I have not used their service. I have asked for my refund in the same day when I have signed up.

READ BEFORE YOU PURCHASE. IT MAY SAVE YOUR MONEY.
This company does not provide 10% of the value it costs. The price to register and integrate to shopify store costs around 350 euros. The pain does not end here, It is also necessary to have Shopify yearly plan to add this courier app with shopify. I was disappointed with their service from the very beginning. Their website has a lot of bugs. So, I reviewed their company with 1 star. Then they emailed and called me to remove the reviews because of Trustpilot. I asked them to cancel my subscription and for a refund. According to their so-called policies they said they can not refund. So, I am writing my honest review of them again.

Scam Warning!!!
I have submitted a complaint report to google to shut down BigBuy's advertisement from their search engine and now I request Shopify to remove this app from their app store. Dear innocent users be aware that BigBuy is a Scam. I lost almost a thousand euros on BigBuy for nothing. They know very well after testing their app nobody is going to purchase it. That's why they don't offer a test version, instead, you have to purchase the connector first of all and pay for a monthly subscription to use their app.
Please be careful and read the reviews here and as well as on google before you buy this app. 99% are complaining about this Scam.

Bigbuy is a complete scam for dropshippers. They list the products themselves and for a lower sell price than the actual cost they give you. So for example if you want to sell a product from them with a cost of 60 euros ou will see that they sell that very same product for less than the cost price, let's say 58 euros. This means it basically makes no sense to sell their products, they do it themselves already and you would need to outcompete them. Cost me a lot of time to translate their stupid product descriptions and also advertising moneyy until i realized i have no chance to even get even. ABSOLUTE SCAM, STAY AWAY

Spent time reading info and watching videos on their website and contacted them and read the links they sent me and at the end they don't have a trial period for their service!! You have to pay them 219€ once and at least 69€ every month!!! It doesn't sound normal here.
Without knowing the quality of service, cost of shipping and delivery time +++++ ,You have to pay them 288€ and you can never return it if you are not satisfied with the service.. I will never do that.
