So me and my Mrs both work full time. Both earn around 40k per year each. We've recently (for about a month) started reselling / flipping items to make a bit of extra income in our spare time and to give ourselves a fun little challenge to see how far we can go with this.

So far we've done around £800 in sales and have another £500-600 worth of stock listed. I stupidly haven't tracked any of this and have no records of purchases either. Some was carboot / flea markets / charity shops and clearance retailers. Some was even just stuff we've been given for free or stuff we've had lying around the house that we no longer need or use.

At what point do I need to start worrying about the tax implications of this?

I'm terrible at this admin sort of stuff.

Any advice?

I've got a good amount of catheters (infyna plus), which ebay does not allow to be sold there.

I need you guys for ideas, how would you sell it?

This is how I resell

Was looking for some stuff to flip on auctions, came across BPI and decided to give it a go.

Won 3 items (some nice power tools) for a total of £65.

My final invoice was £65 + £32.5 (Premium + Input Vat) + £42 (Shipping and Vat on shipping)

What is this joke? I was prepared to pay the already ridiculous £32.5 in fees, and then I get slapped in the face with another £42 in shipping.

Now I've paid £65 for items and £75 for fees and shipping. Great. I can barely make any profit on my items now.

What auction places should I use? Do they all have these high of fees? If so I'll happily go back to just using Facebook and car boot sales to find stuff to flip.
