British Cycling Free Intro Pack - SiS Energy Pack £3.99 del

£3.99 delivery is a joke

£3.99 delivery is a joke

Looks like you get a promo code to take the price off the product, but will still have to pay postage if order is under £30. Delivery costs £3.99. Good deal if you are already buying stuff over £30 on the website, but not for those looking for a quick free bottle and energy sachets.

Not cheeky at all, it states in the terms the offer is open to everyone, nowhere does it say you have to be a member to qualify for it

£3.99 is a lot for postage of some sachets!
Would be a good deal if you found something that was a great deal for £10 that you wanted anyway from here and got the gel for free.
You can buy 20 gels for £7.99 so this is more like going price for these rather than being free!…HAQ

I've now had 3 of these, all horrible the high5 gels taste far better, but agree flapjack or the like seem to work well,

Ordered mine yesterday arrived today. Faultless delivery

Hey Farmer Giles sportive "athletes", tuck your arms and knees in and get … Hey Farmer Giles sportive "athletes", tuck your arms and knees in and get lower into the drops. Then you'll arrive before the point at which you think you need some food and can avoid having to pay even £3.99 extra...If even 1% of the people I see out were to actually benefit from these, I'd be utterly amazed. Top amateurs, pros, for sure - but generally, a decent meal beforehand will see you through your ride! Save your bloody cash and stop complicating everything. Just ride.

I need to replenish my energy when doing a long ride of 100 mls; personally I don't like the gels but use energy bars / biscuits etc. If you do ultra marathons etc then maybe yes you don't need to eat for long rides - good for you but you will be the very small minority..

Received yesterday, surprised that they honoured it TBH. Thanks OP.

received my order (which was supposed to be some missing items from my original order) today... and once again: items are not as expected.. there was supposed to be 20 energy gels, but they sent me 10 energy gels + 8 energy bars.

Also just had an reply from my email telling them about the mistake in my order and they told me they would send replacements out and they would be with me in 3-5 days, the whole place is in a bit of a mess with these orders so hopefully i'll get 2 new lots sent out

Just got off the phone to Science in Sport (contact number 01282 440980 if anyone needs it) and they re-ordered the missing items for next day delivery and didn't ask for the stuff they sent by accident back - bonus

got my order today, two seperate boxes - half was correcr, the other half totally different to what I ordered - and not something I want - so I have emailed customer service this evening and will give them a ring in the morning

The best price I've ever managed to buy SIS tablets was £3.50 on amazon … The best price I've ever managed to buy SIS tablets was £3.50 on amazon in August last year, so £2.84 is certainly a great price if you buy SIS. Not a big fan of high5 gels or tabs myself, but you can get them cheap in Lidl sometimes.[img][/img]

That is a great price.
